Explain how you find a unit rate when given a rate.

This can be illustrated with an example:-

A car travels 100 miles in 2 hours

rate = 100 miles per 2 hours

unit rate = number of miles per ONE hour

so the unit rate in this case = 100/2 = 50 miles per hour.

Unit rate is the distance travelled in unit time. In this case the unit is an hour.
