If a truck goes 30 miles in 30 minutes, what is its average speed? *

The average speed is 60 miles per hour or 1 mile per minute.

Explanation:

If you multiply 30 by 2 to find the miles per hour, you also have to multiply 30 miles by 2. This results in 60 miles per hour. If you want to find the miles per minute, you divide the 30 minutes by 30. You have to do the same to the miles, so the average speed could also be 1 mile per minute.
