Question

a hundred metre long train crosses a bridge of length 200m in 50 seconds with constant velocity . find the velocity

Answer 1

total distance=200+ 100=300
velocity
$= \frac{300}{50} = 6$

Answer 2

hello here is your answer
v= s/t

here train is 100 m long and bridge 200 m therefore, s= 300m
time= 50 seconds

v= 300/50
v=6m/s

hope it helps!!
