Question

Jen and her grandfather walked 1/2 of a mile in 10 minutes. At this rate, how long will it take them to walk 1 1/12 mile to the park

Answer 1

21 minutes and 40 seconds

Explanation:

A couple ways to do these, but probably the most straightforward is to find their walking rate:

0.5 miles in 10 minutes is 0.05 miles per minute

Then divide 1 1/12 miles by 0.05 miles per minute to get minutes, the amount of time it takes them. (Are you sure it's 1 & 1/12 miles? Because that's sort of a weird fraction.)

Put it in your calculator and you'll get 21.6666 minutes, which they'll probably want you to state as 21 2/3 minutes, or 21 minutes and 40 seconds.
