The length of the bridge, which a train 200 metres long and travelling at 60 km/hr can cross in 30 seconds, is?
Answer/Solution
370 m.
Steps/Work
Speed = [60 X 5/18] m/sec = [50/3] m/sec Time = 30 sec Let the length of bridge be x metres. Then, (130 + x)/30
= 50/3 => (130 + x)/30
= 370=> x
= 370 m.
Answer:D
= 50/3 => (130 + x)/30
= 370=> x
= 370 m.
Answer:D
