An object Tranels 20 minute in 5 second
and then other 20 minute
in 4 seconds what is the average speed of the object
​

Answer 1

Explanation:

Average speed = (speed in 1st interval + speed in 2nd interval) ÷ 2

We know that ,

Speed = distance/time.

Speed of object in 1st interval = 20/4 = 5 m/s

Speed of object in 2nd interval = 20/10 = 2 m/s

Average speed = (5+2)/2 = 3.5 m/s
