Answer:
She spends 2 hours driving.
Step-by-step explanation:
The formula given is:
[tex]d = rt[/tex]
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 [tex]d = 80, r = 50[/tex]
To the nearest hour, how many hours does she spend driving?
We have to find t. So
[tex]d = rt[/tex]
[tex]50t = 80[/tex]
[tex]t = \frac{80}{50}[/tex]
[tex]t = 1.6[/tex]
Rounding to the nearest hour
She spends 2 hours driving.
