Given,speed 1=30km/hr
speed 2=45km/he
Time taken=x
Therefore,av speed = total displacement covered÷total time take
=0/x
(displacement= 0,
because the train
comes back to
its original
position)
=0km/hr
Therefore, average speed =0(km/hr)
speed 2=45km/he
Time taken=x
Therefore,av speed = total displacement covered÷total time take
=0/x
(displacement= 0,
because the train
comes back to
its original

=0km/hr
