Answer 2

Hello mate..

Here Is Your Answer:

GIVEN:

Length of the train = s = 50m.

Speed of the train = v = 10m/s.

Therefore,

time taken to cross the electric pole:

$\bold{t = \frac{s}{v} = \frac{50}{10}} \\ \bold{ = 5s}$

Distance travelled while crossing the bridge

→length of train + lenght of the bridge.

=> 50 + 250 = 300m.

Time taken to cross the bridge

$\bold{=> \frac{300m}{10m/ s} } \\ \bold{ = 30 \: seconds.}$

HOPE THIS HELPS YOU..
