Last Sunday, Mr. Stone drove 320 miles in 5 hours. What is the unit rate per hour?
To find the unit rate per hour, we need to divide the total distance traveled by the total number of hours. In this case, Mr. Stone drove 320 miles in 5 hours.
The formula to find the unit rate per hour is:
Unit Rate = Total Distance / Total Time
Applying this formula, we have:
Unit Rate = 320 miles / 5 hours
Dividing 320 by 5 gives us:
Unit Rate = 64 miles per hour
So, the unit rate per hour for Mr. Stone's journey is 64 miles per hour.
