Explanation
How long does a train 110 meters take to cross a bridge 132 meters in length?
Total length = 110 + 132 = 242 meters
Speed is given in km/h but length is meters so speed will be changed to m/sec.
In order to figure out time
Time = distance/speed
To Find
Time = ?
Solution
Given speed = 72 km/h
Speed in m/sec = (72 x 1000)/3600
Speed in m/sec = 20 m/sec
Total length = 110 + 132 = 242 m
Now,
Time = distance/speed
Time = 242/20
Time = 12.1 sec answer
Conclusion
A train 110 meters long running at the speed of 72 km/h takes 12.1 seconds to cross a bridge 132 meters in length.
