Use the conversion 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 conversion ratio of 1 kilometer equaling about 0.62 miles.

The airplane travels at a rate of 900 kilometers per hour.

To convert this to miles per hour, we multiply the distance in kilometers 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.
