Two Trains 130 And 110 Meters Long Are Going In The Same Direction. The Faster Train Takes One Minute To Pass The Other Completely. If They Are Moving In Opposite Directions, They Pass Each Other Completely In 3 Seconds. Find The Speed Of The Faster Train? |

Answer» Total Distance to be travelled by both the trains = 130 + 110 = 240m Let ‘F ’and ‘S’ be the speeds of fast and slow trains in m/sec. 240=60(F-S), 240= (F+S) In the same direction, F – S = 4 m/sec …… (1) In the opposite direction, F + S =80 m/sec…… (2) Solving them we get F = 42 m/sec. Total Distance to be travelled by both the trains = 130 + 110 = 240m Let ‘F ’and ‘S’ be the speeds of fast and slow trains in m/sec. 240=60(F-S), 240= (F+S) In the same direction, F – S = 4 m/sec …… (1) In the opposite direction, F + S =80 m/sec…… (2) Solving them we get F = 42 m/sec. |
