Kevin can travel 22 1/2 miles in 1/3 hour. What is his average speed in miles per hour?
Nataly_w [17]
The easist way i can think of doing this would be to multipy the 22.5 miles by three so you can see how far he would go if he had one hour to travel at that average speed, the answer after multipying by 3 is 67.5 miles per hour, which in most plavces he would b considered speeding.
