Answer:

It took Ben 5 hours to drive the distance.

Step-by-step explanation:

D - distance

t - time

r - rate

Use formula [tex]D=r\cdot t[/tex] 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:

[tex]325=65\cdot t\Rightarrow t=\dfrac{325}{65}=\dfrac{65\cdot 5}{65}=5\ hours[/tex]
