Question

Change the speed of 6m/so into km/have?

Answer 1

We know that ,
1Km = 1000m
1 hour = 3600 sec

1Km/1hr = 1000m / 3600 sec = 5/18 m/s

Then, 1 m/s = 18/5 Km/hr

6 m/s = 6 × 18/5 Km/hr

6 m/s = 108/5 Km/hr

6 m/s = 21.6 Km/hr

Remember when you have change to Km/hr, Multiply by 18/5.

And when you have change to m/s, Multiply by 5/18.
