Question

Ben drove 325 miles at a rate of 65mph. How long did it take him to drive the distance? What do we know? What is the unknown (what are we trying to find)? Choose a variable for the unknown.

Answer 1

It took Ben 5 hours to drive the distance.

Explanation:

D - distance

t - time

r - rate

Use formula
`D=r\cdot t` connecting the distance, the time and the rate.

In your case, we know

distance D = 325 miles

rate r = 65 mph

and do not know time.

Substitute them into the formula given above:

`325=65\cdot t\Rightarrow t=(325)/(65)=(65\cdot 5)/(65)=5\ hours`
