Question

a train of length 50m is moving with a constant speed of 10m/s calculate the time taken by the train to cross an electric pole and a bridge of length 250m plzz answer​

Answer 1

Explanation:

Distance covered by train the cross the bridge (from front of engine to back of last wagon )

d=250+50=300 m

Speed of train v=10 m/s

Thus time taken t= distance /speed

t=300/10

=30second @nswer:)

Answer 2

Answer:

HELLO FRIEND✨️✨️ YOUR ANSWER↷↷

Length of the train ➨50m;

Speed of the train➨ v =10m/s.

Distance travelled while crossing an electric pole ➨

Length of the train➨s=50m.

➨ Time taken to cross the electric pole 't' = s/v ➨

t ➨50/10=5sec.

Length of the bridge ➨ 250 m.

Distance travelled while crossing the bridge➨

= Length of train± Length of bridge

= 50±250=300m.

➨ Time taken to cross the bridge ➻ 300/10m/s

➻30seconds
