For a car that travels 70 mph for 60 miles and then 80 mph for
60 miles. The total time traveled is given by calculating the
distance per rate traveled for each part and then summing the
values. •Have the program in c++ that calculates the most
appropriate mean rate of the two different rates and the two equal
distances, and output the result to the text file. The “best” mean
rate is the rate at which T=D/R is same...
