Use the conversation ratio 1 kilometer equals about 0.62 miles to solve the following problem. An airplane travels about 900 kilometers per hour. What is the airplane's speed in miles per hour?

Answer 1

To find the airplane's speed in miles per hour, we can use the conversation ratio to convert kilometers to miles:

1 kilometer = 0.62 miles

The airplane travels at a speed of 900 kilometers per hour. To find the speed in miles per hour, we multiply 900 by the conversion ratio:

900 kilometers/hour * 0.62 miles/kilometer = 558 miles/hour

Therefore, the airplane's speed is approximately 558 miles per hour.
