Answer:

Explanation:

Given that, an object moves 20 metre in 4 seconds.

So, distance (d1) = 20 m and time (t1) = 4 sec

Also given that, then object travels in 20 metre in 2 seconds.

Now, distance (d2) = 20 m and time (t2) = 2 sec

We have to find the average speed of the object.

Average speed = (Total distance)/(Total time)

Total distance travelled by an object = d1 + d2

= (20 + 20)m

= 40 m

Total time taken by an object = t1 + t2

= (4 + 2) sec

= 6 sec

Average speed = 40/6 = 6.67 m/s

Therefore, the average speed of the object is 6.67 m/s.
