Question

4. How much time will it take if a 300m.
long train covers a 200 m. long bridge
with a speed of 25m./sec?​

Answer 1

Answer:

The bridge's length = 200m

The train's length = 300m.

Kindly note the entire train including the last wagons should cross the bridge. Hence, the total distance to be travelled = 200m + 300m = 500m

Speed of Train = 25m/s.

Therefore, Time = Distance/Speed = 500m/ 25 = 20second

Answer = (c) 20 sec.

Answer 2

Answer:

20 sec

Step-by-step explanation:

Toto distance =200m+300m

=500m

time=distance\speed

500/25=20 sec
