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 convert from kilometers to miles, we can use the given conversion ratio:

1 kilometer = 0.62 miles

To find the airplane's speed in miles per hour, we can multiply its speed in kilometers per hour 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.
