Question

What is the speed of a body which is found to cover a distance of 20m in 4s? ​

Answer 1

Given:

• Distance covered by body ,d = 20 m

• Time taken,t = 4 s

To be calculated:

Calculate the speed of a body?

Formula used:

Speed = Distance/Time

Solution:

We know the distance and time. So, we can calculated the speed by using the formula:

Speed = Distance/Time

★ Putting the values of distance and time, we get

Speed = 20 m / 4 s

= 5 m/s

Thus,the speed of a body is 5 metres per seconds.

Knowledge Enhancer:

Speed: Distance covered by a body per unit time is called Speed.

• S.I unit of speed is m/s or ms-¹

• Scalar quantity
