Mrs. Perales drove 138 miles in 6 hours. What is the unit rate?
Pls help me

 23 miles per hour

Another way to get a unit rate is the number of minutes it takes to travel 1 mile.  1 mile takes her about 2.61 minutes miles to drive.

Step-by-step explanation:  Divide the number of miles by the time  to get the unit rate in miles per hour.

138 ÷ 6 = 23 miles per hour.

If you divide the minutes by the distance, you get the unit rate in minutes per mile.

6 hours is 360 minutes.  60 minutes per hour is a unit rate.

138 ÷ 360  ≈ .3833 miles per minute

360 ÷ 138 ≈ 2.61 minutes per mile
