Question

1 A scooterist covers a distance of 3km in 5 minutes Calculate
hisnspeed in:a) cm/s b) m/s c) km/h

Yash Singh · Accepted Answer

1km=100000cm
so,3km=300000cm
1minute=60 seconds
5min =300 seconds
a:}speed=distance/time
speed=300000/300
speed=1000cm/s
b:}1km=1000m
so,3km=3000m
time=300sec
speed=distance/time
speed=3000/300
speed=10m/s
c:}10m/sin km/h=10*18/5
therefore,speed in km/h=36km/h
