Answer 2

time taken by bus to travel 27km = 45minutes.

= 45/60 hours ..

therefore speed of bus in km hr= distance/time

= 27×60/45

=1620/45

=36km/hr..

time taken by bus to travel 27km = 45 mins=45×60sec.

distance travelled by bus in 45 mins = 27km

= 2700m..

speed of bus in m/sec =

\frac{2700}{45 \times 60}

45×60

2700

=2700/2700

=1m/sec..

therefore speed of bus in km/hr=36km/hr.

speed of bus in m/sec.=1m/sec..
