Question

Convert 72 km per hour into metre per second

Answer 1

Hey Friend ☺

72 km/hr

= 72 × 1000/60 × 60

[Since 1 km = 1000 m

1 hr = 3600 seconds ]

= 72 × 10/36

= 2 × 10

= 20 m/s

So

72 km/hr = 20 m/s

[ SHORT METHOD :-

to convert km/hr to m/s just multiply it by 5/18

So

72 × 5/18

= 4 × 5

= 20 m/s ] .

Hope it helps you ..!!
