Question

Kelly flies a distance of 2,100 miles. The trip takes 4 hours.

A. What is the airplane's unit rate of speed in miles per hour?
B. At this rate of speed, how many miles will the airplane travel in 13 hours?

Answer 1

A. 525 miles per hour

B. 6825 miles

Explanation:

To get miles per hour you need to divide the 2100 (miles) by 4 (hours). This is because per means the same thing as divide.

2100/4 = 525mph

Since we know now that in one hour Kelly can travel 525 miles we then need to mulitply that by 13 to get the number of miles she traveled in 13 hours.

525x13 = 6825 miles

Answer 2

A: The plane is going 525 miles per hour.

B: In 13 hours the plane will travel 6,825 miles.
