Question

In 4 hours, you hike 10 miles. which unit rate describes your speed on the hike?

Answer 1

Your unit rate is hours

Answer 2

Answer: 2.5 miles per hour (mph)

To get this answer, divide 10 over 4

10/4 = 2.5

You can think of it in terms of this ratio

10 miles: 4 hours

If we divide both parts of that ratio by 4, then we'll have

10 miles: 4 hours

(10/4) miles: (4/4) hours

2.5 miles: 1 hour

Therefore, in one hour, you can walk 2.5 miles. The unit rate is basically the speed in which you can do a task in one unit of time, in this case how far you can walk in 1 hour.
