Answer 1

Answer:LET LENGTH OF BRIDGE BE X

Step-by-step explanations 72km/hr=20m/s speed =distance/time 20=(150+X)/13 on solving X you will get 110

Answer 2

Given,

Speed=72kmh-1=20ms-1

Time=13 seconds

Then,distance =speed*time=20*13metres

=260metres

Given that the length of the train is 150 metres and total distance is 260 metres . the the length of bridge is (260-150) metres i.e. 110 metres.

Length of the Bridge is 110 metres.
