Question

On in-line skates, Bradley skates 4 miles in 48 minutes. At this speed, how long would it take him to skate the entire length of a 12-mile bike path?

Answer 1

Explanation:

`(t)/(12)=(48)/(4)\\ \\ t=144min`

Answer 2

144 minutes

Explanation:

4 goes in 12 3 times so we have to do 48 times 3 too. Which is 144.
