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.
