Max walked three-quarters of a mile in 15 minutes. What was his approximate speed in miles per hour?

Answer 1

Let's start by putting everything in the same units. We know that 15 minutes is 1/4 of an hour (15x4 = 60, 60 minutes per hour).

So Max walked 3/4 miles in 1/4 hours, or 3/4 miles

1/4 hours

We have the same denominator of 4 in the top and bottom parts of the fraction, so multiplying the whole fraction by 4/4 or 1 will eliminate the 4 denominator.

3/4 miles x 4 = 3 miles , or 3 miles per hour is our answer!

1/4 hours 4 1 hour
