Question

The distance a vehicle travels can be found by using the formula d = rt, where d is the total distance traveled, r is the rate of speed, and t is the amount of time spent traveling. Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour. To the nearest hour, how many hours does she spend driving?

Answer 1

She spends 2 hours driving.

Explanation:

The formula given is:

`d = rt`

In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.

Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.

This means that
`d = 80, r = 50`

To the nearest hour, how many hours does she spend driving?

We have to find t. So

`d = rt`

`50t = 80`

`t = (80)/(50)`

`t = 1.6`

Rounding to the nearest hour

She spends 2 hours driving.
