How long does a train 110 m long running at the speed of 36 km/hr takes to cross a bridge 132 m length?
Answer/Solution
24.2 sec
Steps/Work
Speed = 36 * 5/18 = 10 m/sec
Total distance covered = 110 + 132 = 242 m.
Required time = 242/10 = 24.2 sec.
Answer: C
Total distance covered = 110 + 132 = 242 m.
Required time = 242/10 = 24.2 sec.
