Question

An object moves 18 m in the first 3 s , 22 m in the next 3 s and 14 m in the last 3 s what is its average speed ?​

Answer 1

Answer:

6 m/s

Explanation:

The average speed of the object = Avg speed in 1st 3 seconds + Avg speed in 2nd 3 seconds + Avg speed in 3rd 3 seconds /3

Avg speed= Distance/ Time

= (18/3 + 22/3 + 14/3 ) / 3

=54/3/3

=54/9

=6

Hence, the average speed of the object is 6 m/s
