Answer 2

Answer:

x = 4 4/5 minutes

Step-by-step explanation:

We can proportions to solve.  Put distance over time

1/6 miles            1 miles

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

4/5 minutes         x minutes

Using cross products

1/6 * x = 4/5 *1

1/6x = 4/5

Multiply by 6 on each side to get x alone

1/6 * 6 x = 6*4/5

x = 24/5

Changing this to a mixed number

x = 4 4/5 minutes
