hey mate!
1 km = 1000m
and 1hr= 60*60sec
so, 1km/hr = 1000m/60*60
1km/hr= 5m/18sec
also,
2) 1m / sec = in km/ hr
1m= 1/1000km
1sec= 1/60*60hr
so , 1m/sec= 60*60/1000km/hr
1m/sec= 18/5km/hr
1 km = 1000m
and 1hr= 60*60sec
so, 1km/hr = 1000m/60*60
1km/hr= 5m/18sec
also,
2) 1m / sec = in km/ hr
1m= 1/1000km
1sec= 1/60*60hr
so , 1m/sec= 60*60/1000km/hr
1m/sec= 18/5km/hr
thx
