How to Solve Train Passes through a Pole Problems?
When a Train Passes through a Pole or Tree the formulas to find the Time Speed and Distance are given below
Suppose the Length of the Train = x mts
Speed of the Train = y km/hr
Time taken by the Train to Cross a Pole or Stationary Object = Length of the Train/Speed of the Train
= x meters/y km/hr
To Change km/hr to m/sec simply multiply with 5/18.
Solved Examples to Calculate When Train Passes through a Pole
1. A train 200 m long is running at a uniform speed of 75 km/hr. How much time will it take to cross a pole?
Solution:
Length of the Train = 200 m
Speed of the Train = 75 km/hr
To convert it to m/sec multiply with 5/18
= 75*5/18
= 20.83 m/sec
Time taken by the train to cross the pole = Length of the Train/Speed of the Train
= 200 m/20.83 m/sec
= 9.6 sec
Therefore, Train takes 9.6 sec to cross the pole.
2. Find the time taken by a train 350 m long, running at a speed of 60 km/hr in crossing the pole?
Solution:
Length of the Train = 350 m
Speed of the Train = 60 km/hr
Time taken by the Train to cross the pole = Length of the Train/Speed of the Train
= 350m/60 km/hr
To change from km/hr to m/sec multiply with 5/18 i.e. 60*5/18 = 16.66 m/sec
= 350 m/16.66m/sec
= 21.008 sec
Thus, the train takes 21.008 sec to cross the pole.
3. A train is running at a speed of 54 km/hr. It crosses a tower in 7 seconds. Find the Length of the train?
Solution:
Speed of the Train = 54 km/hr
Time taken by train to cross tower = 7 seconds
Length of the Train = Speed * Time
= 54*(5/18)*7
= 105 m
Therefore, the Length of the Train is 105 m
4. A train is running at a speed of 140 km/hr. if it crosses a pole in just 8 seconds, what is the length of the train?
Solution:
Speed of the Train = 140 km/hr
Time taken to cross the pole = 8 seconds
Length of the Train = Speed * Time
= 140 km/hr*8
= 140*(5/18)*8
= 311.11 m
Therefore, the length of the train is 311.11 m
