Answer 1

To convert kilometers to miles, we can use the conversion ratio of 1 kilometer equals about 0.62 miles.

If the airplane travels 900 kilometers per hour, we can find the speed in miles per hour by multiplying 900 by 0.62.

900 x 0.62 = 558

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