s=d/t
=600/5*60
=600/300
=2m/s
1km=1000m
1/1000km=1m
3600s=1hr
1/3600=1s
2*3600/1000=7.2km/hr
=600/5*60
=600/300
=2m/s
1km=1000m
1/1000km=1m
3600s=1hr
1/3600=1s
2*3600/1000=7.2km/hr

T=5 Min, 5*60=300sec
SPEED=DISTANCE/TIME
=600/300
=2m/s
convert m/s to km/sec by formula
2*18/5
=36/5
=7.2km/hr
SPEED=DISTANCE/TIME
=600/300
=2m/s
convert m/s to km/sec by formula
2*18/5
=36/5
=7.2km/hr
