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?
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.
