hint Hint:

2 m/s

The correct answer is: 2

Given:
Displacement of the body = 8m
Time taken = 4s
To find:
The velocity of the body =?
Solution:
$V e l o c i t y space equals space fraction numerator D i s p l a c e m e n t over denominator t i m e end fraction V e l o c i t y space equals space 8 over 4 space equals space 2 space m s to the power of negative 2 end exponent$
Answer:
The velocity of the body is 2ms^-1
