1. 6sec.
2. 7sec.
3. 9sec.
4. 11sec.

Show/Hide Answer

Answer = C - 11sec.
Explanation: peed of the train relative to man =( 68 - 8 )
= 60 Kmph
= 60 x 5 / 18
=50/3 m/sec.
Time taken by it to cover 150 m at (50 /3)m/sec = (112 - 50)kmph
= (150 x 3/50)sec
= 9 sec.

Question - 3:A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long??

= (45/2) m/sec
Length of the train = (45 / 2 x 8) m
= 180 m.

Question - 9:Two trains are moving in opposite directions @ 60 km/hr and 90 km/hr. Their lengths are 1.10 km and 0.9 km respectively. The time taken by the slower train to cross the faster train in seconds is:?
