we know that time is = distance/speed:
here,
distance=length of train =100th
and speed= related speed = speed of train + speed of bird =(23+2)m/s= 25m/s
now time = distance/speed = 100/25= 4s
TIME = 4seconds

distance=length of train =100th
and speed= related speed = speed of train + speed of bird =(23+2)m/s= 25m/s
