Use the conversion ratio 1 km equals about 0.62 miles to solve the following problem an airplane travels about 900 km/h. What is the airplane speed in miles per hour is it 558, 899.38 or One, 451.6 or 1240.
To convert the airplane speed from kilometers per hour to miles per hour, we will multiply the given speed by the conversion ratio of 0.62.
Airplane speed in miles per hour = 900 km/h * 0.62 miles/km
Calculating this, we get:
Airplane speed in miles per hour = 558 miles/h
Therefore, the correct answer is 558.
