Question

Jim drove 455 miles in 7 hours. At the same rate, how many miles would he drive in 5 hours?

Answer 1

Given parameters:

Distance covered = 455 miles

Time taken  = 7 hours

New time taken  = 5 hours

Unknown:

New distance = ?

To solve this problem, we need to define what speed entails.

Speed is a physical quantity and it is distance divided by time.

  Speed  = $\frac{distance}{time }$

In this problem, we first find the rate at which Jim is driving;

          Speed  = $\frac{455}{7}$   = 65miles/hr

Now that we know the rate, we can simply find the new distance;

   New distance  = speed x new time taken

Input the parameters;

      New distance  = 65miles/hr x 5hrs   =  325miles
