Last Saturday, Mr. Stone drove 320 miles in 5 minutes. What is the rate of miles per hour

To calculate the rate in miles per hour, we need to convert the time from minutes to hours.

There are 60 minutes in one hour, so to convert 5 minutes to hours, we divide by 60.

5 minutes / 60 minutes = 0.0833 hours

Now we can calculate the rate of miles per hour by dividing the distance of 320 miles by the time of 0.0833 hours:

320 miles / 0.0833 hours = 3840 miles per hour

Therefore, the rate of miles per hour is 3840 miles per hour.
