4-12.

A car travels 45 mph for 3 hours and 55 mph for the next two hours. Homework Help ✎

How far did the car travel?

Draw a speed vs. time graph of the situation.

What is the area under your curve from 0

*≤ h*≤ 5?How do your answers to part (a) and part (c) compare? Why?

distance = (rate)(time)

(45)(3) + (55)(2)

They are the same because the area under the curve is the distance traveled.
