Question

Brett runs at constant speed, 3 miles every 45 minutes. At this rate, how many mile(s) does he run in 12 minutes?

Answer 1

0.8

Explanation:

To find the answer to this question multiply the rate by the time he runs.

The rate tells us how many miles he runs during certain time. Once given a time, 12 minutes,

we have to multiply the rate which must be expressed as a quotient (3miles/45minutes) times the given time:

`12Min ~x~(3~miles)/(45~Min) =0.8`

It means that he runs 0.8 miles in 12 minutes.
