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

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

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.
