A school bus takes 45 minutes to cover a distance of 18 km calculate its speed in kilometre per hour.

= 45 minutes=45/60 =¾h

= distance covered=18km

=time taken=¾h

therefore speed=(18÷¾)km/h

=(18×4/3)km/h=24km/h.

let express the speed in in m/s.

Distance=18×1000m.

Time=45×60s

=speed =18×1000m/45×60s

=6.6m/s.

The motion of a bus movie on the road is not uniform the bus container Li change direction and its speed is not uniform either it slows down stops at traffic light and bus stops star again and picks up speed so the speed can help calculated is the average speed of the bus this in fact is true of most real life situation generally when we talk about speed women average speed.
