Question

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

Answer 1

Answer:

Step-by-step explanation:

Let ,the length of bridge is x metre

72km/hr=72*5/18m/sec

=20m/sec

we know

D/V=T

D= length of (Bridge+train)

V=20m/sec

T=13 sec

(x+150)/20=13

X+150=260

X=110 metre
