Question:

A child released a balloon into the air 45 minutes ago, and the air forced the balloon to travel 5 miles before another child found it. At what speed did the balloon travel?

A 6.7 mph
Explaination

The balloon traveled at a speed of 6.67 mph. To find the motion of the balloon, you will need to use the following formula: average speed = distance traveled / time to travel distance. For this problem, we will convert the minutes to hours: 45/60 = 0.75 hours. Then, find the rate of speed: 5 miles / 0.75 hours = 6.7 mph.
