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 airplanes speed in miles per hour?

Answer 1

To solve this problem, we can use the conversion ratio to convert the given speed in kilometers per hour into miles per hour.

Given:
1 kilometer = 0.62 miles
900 kilometers per hour

To convert from kilometers to miles, we need to multiply the given value by the conversion ratio:

900 kilometers/hour x (0.62 miles/1 kilometer) = 558 miles/hour

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