Question

A train 150 meters long and running at a speed of 45 kmph crossed a bridge in 48 seconds. Because the train halted on the bridge it took 30 seconds more to cross the bridge. What is the length of the bridge?

Answer 1

length of the train =150m
speed=45km/hr =45*5/18= 12 9/18=225/18m/sec
time =48sec =48-30=18 sec
distance =speed*time
= 225/18*18
=225 m
therefore,225-150
=75 m .Ans
