Question

A car is driving at a rate of 61 miles per hour.

Answer 1

This is distance-velocity-time relationship.

recall that dist = velocity*time

so

velocity = 61 mph

distance = 323.3 mi

so to find time we should divide distance by velocity

t = d/v

t = 323.1/61

= 5.3 hrs (to the nearest tenth)

Answer 2

It will take the car 5.3 hours to drive 323.2 miles.
To get this you simply divide 323.2 by 61.
Which gives you 5.3.
To check this you can do 5.3 * 61. 
This gives you 323.2.

Hope this helps you! (:
