Chapter 13.4, Problem 27E

Distance Traveled An insurance company collected data on the speed of two cars during a particular three-hour window. The accompanying graph shows that the red car was driving at a constant 25 mph throughout this period, whereas the speed of the blue car was increasing.

a. At time $t=1$, was the red car traveling faster than, slower than, or the same speed as the blue car? At time $t=1$, was the total distance traveled by the red car (starting at $t=0$ when data collection began) greater than, less than, or the same as that of the blue car?

b. Repeat part (a) for time $t=2$.

c. Repeat part (a) for time $t=3$.
