4-12.
  1. A car travels 45 mph for 3 hours and 55 mph for the next two hours. Homework Help ✎

    1. How far did the car travel?

    2. Draw a speed vs. time graph of the situation.

    3. What is the area under your curve from 0 ≤ h ≤ 5?

    4. 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.
