- 6. A train 150 m long is running with a speed of 98 kmph. In what time will it pass a man who is running at 8 kmph in the same direction in which the train is going

A.5 sec

B.

**6 sec**C.7 sec

D.8 sec

Answer & Explanation

Answer: Option B

Explanation:**Speed of the train relative to man = (98 - 8) kmph**

= (90× 5/18) m/sec = 25 m/sec

Time taken by the train to cross the man I

= Time taken by It to cover 150 m at 25m

= (90× 5/18) m/sec = 25 m/sec

Time taken by the train to cross the man I

= Time taken by It to cover 150 m at 25m

*/*sec = 150 ×1/25 sec = 6sec- 7. A train 220 m long is running with a speed of 59 kmph.. In what will it pass a man who is running at 7 kmph in the direction opposite to that in which the train is going

A.8 sec

B.10 sec

C.12 sec

D.14 sec

Answer & Explanation

Answer: Option C

Explanation:**Speed of the train relative to man = (59 + 7) kmph**

= 66 ×5/18 m/sec = 55/3 m/sec.

Time taken by the train to cross the man = Time taken by it to cover 220 m

at (55/3) m

= 66 ×5/18 m/sec = 55/3 m/sec.

Time taken by the train to cross the man = Time taken by it to cover 220 m

at (55/3) m

*/*sec = (220 ×3/55) sec = 12 sec- 8. Two trains 137 meters and 163 meters in length are running towards each other on parallel lines, one at the rate of 42 kmph and another at 48 kmpb. In what time will they be clear of each other from the moment they meet

A.8 sec

B.10 sec

C.12 sec

D.14 sec

Answer & Explanation

Answer: Option C

Explanation:**Relative speed of the trains = (42 + 48) kmph = 90 kmph**

= (90×5/18) m

Time taken by the trains to ‘pass each other

= Time taken to cover (137 + 163) m at 25 m /sec = (300/25) sec = 12 sec

= (90×5/18) m

*/*sec = 25 m*/*sec.Time taken by the trains to ‘pass each other

= Time taken to cover (137 + 163) m at 25 m /sec = (300/25) sec = 12 sec

- 9. Two trains 100 meters and 120 meters long are running in the same direction with speeds of 72 km/hr, 54 km/hr In how much time will the first train cross the second

A.36 sec

B.40 sec

C.44 sec

D.46 sec

Answer & Explanation

Answer: Option C

Explanation:**Relative speed of the trains = (72 - 54) km/hr = 18 km/hr**

= (18 × 5/18) m/sec = 5 m/sec.

Time taken by the trains to cross each other

= Time taken to cover (100 + 120) m at 5 m

= (18 × 5/18) m/sec = 5 m/sec.

Time taken by the trains to cross each other

= Time taken to cover (100 + 120) m at 5 m

*/*sec = (220/5) sec = 44 sec.- 10. A train 100 meters long takes 6 seconds to cross a man walking at 5 kmph in the direction opposite to that of the train. Find the speed of the train.

A.45 kmph

B.50 kmph

C.55 kmph

D.60 kmph

Answer & Explanation

Answer: Option C

Explanation:**Let the speed of the train be x kmph.**

Speed of the train relative to man = (x + 5) kmph = (x + 5) ×5/18 m/sec.

Therefore 100/((x+5)×5/18)=6 <=> 30 (x + 5) = 1800 <=> x = 55

Speed of the train is 55 kmph.

Speed of the train relative to man = (x + 5) kmph = (x + 5) ×5/18 m/sec.

Therefore 100/((x+5)×5/18)=6 <=> 30 (x + 5) = 1800 <=> x = 55

Speed of the train is 55 kmph.
