Question 1165976
.
It took Jim 25 minutes to ride to the bicycle shop and 1 hour and 15 min to walk home. 
If he can ride his bike 8 km/hr faster than he can walk, how far is the repair shop?

<pre>
Another way to solve the problem is to notice that 1 hour and 15 minutes is  75 minutes

and the ratio of traveled times is  {{{75/25}}} = 3.


It means that the rate cycling is 3 times the rate walking,

So, the rate cycling is 3x, where x is the rate walking.


But the difference of the rates is

    3x - x = 8 km/h,   or

    2x     = 8 km/h,

     x     = 8/2 = 4 km/h.


So, to find the distance, multiply the rate walking, or 4 km/h, by the time walking, which is 1 hour and 15 minutes, ot {{{5/4}}}  hours.
You will get then the distance = {{{4*(5/4)}}} = 5 kilometers.    <U>ANSWER</U>
