Problems on Trains

  • Trains Questions and Answers
  • 1. A 400m long train is running at 72 Kmph. how much time it will take to cross an electric pole? 

Answer: Option 'B'

Formula: Distance = Speed × Time
If we convert Kmph in to Mpsec multiply by 5/18,
400 = 72 KmpH × time
400 = 72×5/18 × time
Time = 20Sec

  • 2. A 180m long train is running at 54 Kmph. how much time it will take to cross a platform of 120m long? 

Answer: Option 'A'

Formula: D = S × T 
180 = 54 Kmph × Time 
180= 54×5/18 × Time 
Time = 20 Sec 

  • 3. 320m long train is running at 72 Kmph. how much time it will take to cross a platform of 180m long? 

Answer: Option 'B'

Total Length = platform Length+ Train Length 
Total Length= 500m 
D = S × T 
500 = 72 × time 
500 = 72 × 5/18 × time 
Time = 25Sec 

  • 4. A 600m long train is running at 90 Kmph. how much time it will take to cross an electric pole? 

Answer: Option 'C'

Formula: D = S × T 
600 = 90 Kmph × T 
600 = 90 × 5/18 × T 
Time = 24Sec

  • 5. Two trains 300m and 400m long run at the speeds of 40 kmph and 50kmph respectively in opposite Directions on parallel tracks. The time taken to cross each other? 

Answer: Option 'D'

Length of two Trains = 300m + 400m = 700m 
Total Speed= 40 Kmph + 50 Kmph (Opposite Direction)
= 90 Kmph 
Time = Distance/Speed 
Time = 700/ 90 
Time = 28Sec
