Train – A crosses a stationary train –B in 35 seconds and ...
Ans-420m
time taken to cross a pole=14secs
distance covered=length of trainA=280m
s=d/t
s=280/14 =20m/s

now,
speed of train A= speed of train B=20m/s
distance covered= length of train A+length of trainB=x+280
time=35s
20=x+280/35
x=420m
