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?
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.
