A pilot flew a jet from City A to City B, a distance of 1600 mi. On the return trip, the average speed was 20% faster than the outbound speed. The round-trip took 5 h 20 min. What was the speed from City A to City B?
It took a crew 3 h 44 min to row 7 km upstream and back again. If the rate of flow of the stream was 1 km/h, what was the rowing speed of the crew in still water?

An airplane pilot wishes to fly to his destination 500 mi due
west, but the wind is blowing at 23.1 mi/hr toward 14.1° north of
west. The speed of the plane relative to the air is 166.5 mi/hr. At
what angle (south of west) must the pilot orient the plane in order
to fly to his destination directly?
If the pilot orients the plane at that angle, what will be the
speed of the plane relative to the ground?

(a) A commercial 737 jet transporting 143 passengers and 5 crew
members from Kansas City to Baltimore burned 11,800 lbs. (about
1700 gallons) of Jet A fuel en route. Jet A fuel is kerosine based,
consisting primarily of CnH2n+2 hydrocarbons,
with n = 6 to 16, so the carbon: hydrogen ratio is close to 1:2.
During this flight, how much CO2 was released into the
atmosphere? Assume the combustion of the fuel was complete, so all
the fuel was burned...
