Question

Cho is driving a car. He gets to his destination, which is 72 miles away, in 1 hour and 30 minutes. a. The equation d = rt can be used to model Cho’s drive, where d is the distance traveled, r is the speed of the car, and t is the amount of time spent traveling. Substitute Cho’s time and distance into the equation.

Answer 1

50 miles per hour

Explanation:

In this question, we are asked to substitute the information given into the equation. First we need consistency on units. Hence the 1hr 30 minutes is same as 1.5hrs

Now since d =rt

We need to get r = d/t

This means r = 75/1.5 = 50 miles per hour
