Question

An object travels a distance of 16 m in 4s and then another 16m in 2 s. What is the average speed of the object?

Answer 1

average speed = total time taken

Answer 2

1st object travals in 4s =16m
so in 1s =16/4=4m
2nd object traval in 2s =16m
so in 1s = 16/2= 8m
average speed = 8m+4m / 2
=12m / 2
= 6m ans
