Answer 1

Answer:

If we want to convert from km/hr to metre per second we multiply speed in km/hr by 5/18

It is an easy trick to remember and very helpful

1) 144 km/hr

= 144 x 5/18 = 40 metre per second

2) 216 km/hr

= 216 x 5/18 = 60 metre per second

3) 360 km/hr

= 360 x 5/18 = 100 metre per second

4) 180 km/hr

= 180 x 5/18 = 50 metre per second

5) 1152 km/hr

= 1152 x 5/18 = 320 metre per second
