Question

convert 70 km/hr to m/s and show the process
​

Answer 1

Explanation:

km/hr to m/s

1 km =1000m

1hour=60×60 sec

m/s=1000÷3600

m/s=5÷18

70×5÷18

19.444444........

Answer 2

Answer:

70 km/h

1 km = 1000 m

1 hr = 3600 sec

70x1000/3600

70x10/36

70x5/18

350/18

19.45 m/s

and instead of taking 1000/3600

when we are converting km/hr to m/s

we take 5/18

and when we converting m/s to km/hrs

we can take 18/5
