What's the airplane velocity when it flies 100 miles in 20 seconds

Speed = distance / time

The airplane's speed is

(100 miles) / (20 seconds)

That's 26,400 feet per second,

5 miles per second,

300 miles per minute,

18,000 miles per hour.

There's not enough information to describe the airplane's velocity. For that, you need to know what direction it's flying.

Answer : 5m/s

Explanation:the formular for velocity is distance / time or you can say displacement / time. Then it would then be

100/20 = 5m/s
