Question

A train takes 10 sec to cross a pole and 20 sec to cross a platform of length 200 m. Find the
length of the train.
​

Answer 1

Answer:

200mts

Step-by-step explanation:

L = 10 x 20 = 200 mts.

Hence, the length of the train = 200 mts.

Answer 2

Answer:

Distance= Speed * Time

Speed = Distance/Time

Train took 20 sec to cross 200 meter platform

Speed Of Train = 200/20 =10m/sec

Train took 10 sec to cross a pole.Sine we know that train is traveling with a speed of 10m/s.The distance train travelled from the pole is equal to it's length

Hence Length= Speed *Time =10*10=100m

Length of train =100m
