Question

A BUS TRAVEL 54 KM IN A 90 MIN .FIND THE SPEED OF THE BUS

Answer 1

Given:

distance=54kms

time=t=90mins

1hr=60min

1min=1/60hr

t=90/60=1.5hr

Speed=distance/time

=54/1.5=36Km/hr

1km/hr=5/18m/s

speed=36x5/18=2x5=10m/s

Therefore, speed is 10m/s

Answer 2

distance =54×1000=54000 m

time =90×60=5400 sec

speed =d/t

s =54000/5400 =10 m/sec
