Maths Puzzle
find the time require for a train of length 150 meters traveling at 36 km/hr to cross a person standing on the platform of length 300 meters.
Read Solution (Total 3)

- speed = 36 km/hr = 36*5/18= 10m/sec
Time taken by train of length 150 meters traveling at 36 km/hr to cross a person = 150/10 = 15 secs.
length of platform is not important as qn is about time taken by train to cross person only.
