Question

change the speed of 6m per second into km per hour

Answer 1

Hello,
To convert m/sec into km/hr , multiply the number with 18 and then divide it with 5.
This comes as,
1m = 1/1000km
1sec= 1/3600hour
So,
1m/sec = 1/1000/1/3600 km/hour
= 3600/1000 km/hour
= 18/5 km/hour

Therefore, with the given Sum,
6×18 = 108/5=21.6km/hour (Ans)

Thank you
