Question

The distance your friend travels y (in miles) running x hours is represented by the equation y=7.5x. How many minutes does it talks for your friend to run one mile?

Answer 1

The first thing we must do is replace y = 1 in the equation and clear the value of x:
 1 = 7.5x
 Clearing x:
 x = 1 / 7.5 = 0.13 h
 Then, you should keep in mind the following conversion:
 1h = 60min
 x = (0.13) (h) * (60/1) (min / h) = 7.8 min
 answer:
 It will take 7.8 minutes to travel 1 mile
