Question

CLER
what is velocity of a body travels a distance a distance
of 168 metres in a line in 21 second
?​

Answer 1

speed = distance/time = 168/21 = 8m/s

Answer 2

Given :-

Displacement of the body = 168 m

Time taken by the body = 21 sec

To Find :-

The velocity of the body.

Analysis :-

Here, we are given with the displacement and the time taken.

Substitute these values given in the formula of velocity equals displacement divided by total time and find the velocity accordingly.

Solution :-

We know that,

• s = Displacement
• t = Time
• v = Velocity

Using the formula,

$\underline{\boxed{\sf Velocity=\dfrac{Displacement}{Total \ time} }}$

Given that,

Displacement (s) = 168 m

Total time (t) = 21 sec

Substituting their values,

v = s/t

v = 168/21

v = 8 m/s

Therefore, the velocity is 8 m/s.
