For ME12 Aim: How to calculate with D = RT formula?

Homework: Do side 2 of handout- All questions.

Lesson Review:

Example: Two cars start from the same point at the same time and travel in opposite directions.
The slow car travels at 28 mph,and the fast car travels at 35 mph. In how many hours will the cars be 252 miles apart?

Let h = the number of hours traveled by each car.
First fill in the rate and time for each car.
Then represent the distance for each car.
(mph) (hr) (mi)
Rate times Time equal Distance
Slow car 28 times h = 28h
Fast car 35 times h = 35h
The total distance traveled is 252 miles
28h + 35h = 252
63h = 252
h = 4 Solution is 4 hours
