100m long train croses 100m long platform in 10 seconds. what is the speed of the train
Answers
Answer:
Let suppose the pole as a point, and the length of the train is 100m as given, and we know that it crosses that pole in 10s.
• The formula to calculate velocity is = distance/time
(v = d/t) -> v - velocity, d - distance, t - time
• distance=100m, time=10s
• Velocity = 100/10 = 10m/s
• or 10×18/5 = 36km/h
Hope it helps you to understand this :)
Length of the train is 100 m and time taken to cross the pool is 10 sec so divide 100 by 10 you will get the velocity of train to be 10 m/s and if you want convert m/s to km/hr multiply by 18/5 abd the result comes out to be 36 km/hr.
Note- if in place of pool a station is given then the problem will be a bit different. If the question says it takes 10 sec to cross a platform of length 100 m then you have to add the length of train and length of platform and divide the sum by time taken.
