Question

Jeremy can grow 2/3 of a mile in 1/2 of an hour. How long will it take him to roll 1 mile?

Answer 1

Answer: 3/4ths of an hour.

Explanation:

So we know he grows 2/3rd of a mile in half an hour, but we want to find the time to grow 1 mile at his current rate.

Let's make a ratio of miles to hours

2/3 : 1/2

4 : 3

1: 3/4

So, he can grow 1 mile in 3/4ths of an hour.
