Heya !!!

This is your answer....

Given Speed = 150 m/s.

We have to express it into km/h.

1 m = 1/1000 km
1 sec = 1/3600 hr.

So.....

$150 \: \frac{m}{s} \\ = \frac{150 \times \frac{1}{1000 \: } km}{ 1 \times \frac{1}{3600} hr} \\ = \frac{150 \times 3600}{1000} \\ = 15 \times 36 \\ = 540 \: \frac{km}{h}$
Hence 150 m/s is 540 km/h.

Hope you got it ......
