Question

A school bus takes 45min to cover a distance of 27km. Calculate the speed in km/hr and m/s​

Answer 1

time=45 minute= 45/60 = 0.75

dist= 27 km

so, speed = dist/time

= 27/0.75 = 36 km/h

in m/s

time = 45 *60 =2700 sec

dist = 27 *1000 = 27000

so, speed = 27000/2700 = 10 m/s

Answer 2

The time taken by to be travel 27km=45min

45\60 hours

There for speed of bus in km hour=distance÷time

27×60/45=1620/45

=36km

Time taken by bus travel 27=45min=45×60

Distance travel by bus in min=274

=2700 min

speed of bus min/sec=

2700/45×60

=2700/2700

= 1m/sec
