3. A plane travels at a constant speed. It takes 6 hours to travel 3,360 miles. (20 points) a. What is the plane's speed in miles per hour?
b. At this rate, how many miles can it travel in 10 hours?

a. The plane's speed in mph is 560

b. At this rate, the plane can travel 5,600 miles in 10 hours.

Step-by-step explanation:

In order to find the planes speed in mph, some simple arithmetic must be done and you should divide 3,360 by 6.   Now that you have determined that 3,360/6 equals 560, you know that in order to figure out how many miles the plane can travel in 10 hours, all you must do is multiply 560 by 10 which equals 5,600.
