1,451.6
To solve this problem, we need to multiply the airplane's speed in kilometers per hour by the conversion ratio of 0.62 miles per kilometer.
So, 900 kilometers per hour multiplied by 0.62 miles per kilometer equals 558 miles per hour.
Therefore, the airplane speed in miles per hour is 558. Answer: 558.
