2008 Summer Olympics in Beijing, China, in a world record of 9.58 seconds. That works out to be about 23.4 miles per hour over the course of the race. For a brief period during that sprint, Bolt reached an astounding 40 feet per second (27.51 mph). As a physical activity, running is very different from walking. In running, a person's legs flex and the muscles stretch and then contract during acceleration. As the runner's muscles release and absorb energy, the overall energy in the person's body changes and leads to increased speed. What Makes An Elite Runner? Scholars believe that the fastest runners — the elite sprinters like Bolt - are those who use a low amount of energy for every foot that they run, compared to other people. The ability to do that is influenced by a number of different factors, including their age, sex and distribution of muscles. The fastest of the elite runners are young men. The way in which a person's body moves in time and space is called biomechanics. The possible speed of a runner is influenced by their biomechanics, especially how their legs move as they run. Many different factors could influence a person's running speed, including how much time the foot spends touching the ground, how far the legs swing and the angle and distance of the stride. In particular, sprint runners maximize their acceleration and top speed by applying more force relative to their body weight. Their ankles move faster and they take more steps per minute. Long-Distance Runners: When considering speed, sports researchers also look at long-distance runners, who race distances between 3 and 26 miles. The fastest of these runners use considerable plantar pressure, which is the amount of pressure the foot puts on the ground. Changes in biomechanical factors, or how the legs move over time and space, also seem to have a significant effect. As with sprinters, the fastest group in marathon running is men aged between 25 and 29. Those men have an average speed between 558 and 577 feet per minute. This information was gathered from the marathons that were run in Chicago and New York between 2012 and 2016. The New York City marathon runs in waves. There are four groups of runners who begin the race roughly 30 minutes apart. As a result, statistics are available for runner speeds at 3-mile segments throughout the race. Researcher Zhenquan Lin and his team used that data to show that one factor of speed is competition. Runners increase speed and change positions more frequently at the end of the race. The Upper Limits In comparison to other animals, humans are very slow. The fastest animal on record is the cheetah, which can run up to 70 mph. Even Usain Bolt can only attain a fraction of that. Recent research on the most elite runners has led sports medicine expert Peter Weyand and his team to suggest that the upper limit might reach 35-40 mph. So far though, no one has been willing to confirm that in an official publication. In other words, scientists still need to find more Proof. Statistics: According to Rankings.com, the fastest three male sprinters in the world today are Usain Bolt, Tyson and Asafa Powell. Bolt and Powell are Jamaican, and tyson is American. Bolt set the 100-meter record at the 2008 Summer Olympic Games in Beijing, China, completing the race in 9.58 seconds. His speed was 34.25 feet per second. tyson's fastest time is 9.69 seconds. Powell's is 9.72 seconds. The fastest three female sprinters are Florence Griffith Joyner, Carmelita Jeter and Marion Jones, who are all American. Joyner's fastest time in the 100-meter was 10.49 seconds, set in the 1988 Olympics in Seoul, South Korea, at a speed of 31.27 feet per second. Jeter's fastest time is 10.64 seconds. Jones' is 10.65 seconds. The three fastest male marathon runners are, according to Runners World, Dennis Kimetto of Kenya, Kenenisa Bekele of Ethiopia and Eliud Kipchoge of Kenya. Kimetto set the record for the fastest marathon time at the Berlin Marathon in 2014. He completed the 26.2-mile race in just 2 hours, 2 minutes and 57 seconds. Bekele finished the Berlin Marathon in 2:03:03 in 2016. Kipchoge ran the London Marathon in 2:03:05 in 2016. The three fastest female marathon runners are Paula Radcliffe of England, Mary Keitany of Kenya and Tirunesh Dibaba of Kenya. Radcliffe completed the 2003 London Marathon in 2:15:25. Keitany completed the 2017 London Marathon at 2:17:01. Dibaba finished the same race in 2:17:56.

The U.S. Geological Survey compiled historical data about Old Faithful Geyser (Yellowstone National Park) from 1870 to 1987. Let x₁ be a random variable that represents the time interval (in minutes) between Old Faithful eruptions for the years 1948 to 1952. Based on 9520 observations, the sample mean interval was x₁ = 61.2 minutes. Let x₂ be a random variable that represents the time interval in minutes between Old Faithful eruptions for the years 1983 to 1987. Based on 25,340 observations, the sample mean time interval was x₂ = 71.2 minutes. Historical data suggest that σ₁ = 8.35 minutes and σ₂ = 12.41 minutes. Let μ₁ be the population mean of x₁ and let μ₂ be the population mean of x₂.

(a) Compute a 95% confidence interval for μ₁ – μ₂. (Use 2 decimal places.)

(b) Comment on the meaning of the confidence interval in the context of this problem. Does the interval consist of positive numbers only? negative numbers only? a mix of positive and negative numbers? Does it appear (at the 95% confidence level) that a change in the interval length between eruptions has occurred? Many geologic experts believe that the distribution of eruption times of Old Faithful changed after the major earthquake that occurred in 1959.

Because the interval contains only positive numbers, we can say that the interval length between eruptions has gotten shorter.

Because the interval contains both positive and negative numbers, we can not say that the interval length between eruptions has gotten longer.  

We can not make any conclusions using this confidence interval.

Because the interval contains only negative numbers, we can say that the interval length between eruptions has gotten longer.

                                                                      8                                             $40,200

On July 28, Speed World sold four Kazomma 900 dirt bikes to the Vince Wilson racing team. The remaining four bikes remained in inventory at September 30, the end of Speed World’s fiscal year.

Assume that Speed World uses a perpetual inventory system.

a. Compute the cost of goods sold relating to the sale on July 28 and the ending inventory of Kazomma 900 dirt bikes at September 30, using the following cost flow assumptions:

1. Average cost

2. FIFO

3. LIFO

Show the number of units and the unit costs of each layer comprising the cost of goods sold and ending inventory.

b. Using the cost figures computed in part a. answer the following questions:

1. Which of the three cost flow assumptions will result in Speed World Cycles reporting the highest net income for the current year? Would this always be the case? Explain.

2. Which of the three cost flow assumptions will minimize the income taxes owed by Speed World Cycles for the year? Would you expect this usually to be the case? Explain.

3. May Speed World Cycles use the cost flow assumption that results in the highest net income for the current year in its financial statements, but use the cost flow assumption that minimizes taxable income for the current year in its income tax return? Explain.
