Question

a 100 m long train crosses a bridge of length 200 m in 50 seconds with constant velocity. find the velocity​

Answer 1

Answer:

as the total distance = length of train + length of bridge

Explanation:

velocity = total distance/ total time

velocity = 200+100/50

velocity = 300/50

velocity = 6 m/s

Answer 2

Answer:

Distance/Displacement travelled by train to cross the bridge= 300m

It will be 300m because in the question it's mentioned "crosses a bridge",

so, the length of the train would also be considered along with the length of the bridge as the train crosses the bridge.

Time for crossing bridge = 50s

So, Velocity = Displacement/Time

                    = 300/50

                    = 6m/s
