Answer:
A man is standing on a railway bridge which is 180m long. he finds that a train crosses the bridge in 20 sec but himself in 8 sec, the length of the train is and its speed is
Step-by-step explanation:
- The speed (V) of a body is the distance(d) covered by it divided by the time taken (t) to cover the distance
From the question, we have
time taken to cross the man
the length of the train is the distance crossed, let it be x
⇒the velocity of the train (equation 1)
length of the bridge
so total distance covered is
time to cross this distance is
the velocity of the train (equation 2)
velocity is same
⇒
length of the train
speed of the train
