Answer 2

Given:

Speed=20 m/s

To find:

The speed in km/h

Solution:

The required speed is 72 km/h.

We can obtain the required value of the speed by converting it into km/h from m/s.

We know that the given speed can be converted by multiplying it by 18/5.

So, the required speed=speed in m/s×18/5

=20×3.6

=20×36/10

=2×36

=72 km/h

Therefore, the required speed is 72 km/h.
