Answer 1

To convert the speed from kilometers per hour to miles per hour, we can use the conversion ratio 1 kilometer equals about 0.62 miles.

So, to find the airplane's speed in miles per hour:
900 kilometers/hour x 0.62 miles/kilometer = 558 miles/hour

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