Question

6. How can we convert m/s into km/h

Answer 1

Hey friend, Harish here.

Here is your answer:

We know that,

$1m = \frac{1}{1000} km$

$1\ sec = \frac{1}{3600} hours.$

So,

$1\ m/s= \frac{ \frac{1}{1000} }{ \frac{1}{3600} }\ km/hr = \frac{3600}{1000} = \frac{18}{5} km/hr.$

Therefore we must Multiply m/s with 18/5 to convert it into km/hr.
