Answer:

1/5 hour or 12 minutes

Step-by-step explanation:

We can use proportions to solve this problem.  Put the distance over the time

5 km          1 km  

----------- = ---------

1 hour           x hours

Using cross products

5x = 1

Divide by 5

x = 1/5 hour

or if we take it to minutes

1/5 * 60 =  12 minutes
