Question

A train 150 m long is running at 72 km/hr .It crosses a bridge in 13seconds. Find the length of the bridge

Answer 1

Answer:

110m

Step-by-step explanation:

S=D+L

     T

S=72kmph

D=150m

T=13sec

T=13*5/18

let us

72=150+L

     13*5/18

72*13*5/18=150+L

260=150+L

L=260-150

L=110m
