Answer 1

Answer:

1200 m

Step-by-step explanation:

Let the length of the bridge be 'x'

Then the total distance to be covered by the train is going to be its length added to the bridge's length

Total distance = x + 800 m  - (1)

Speed = 60 * 5/18 m/s = 50/3 m/s

Time = 120 s

Hence, distance = speed * time = 50/3 * 120 m = 2000 m

That is, total distance = 2000 m - (2)

Substituting in equation 1, 2000 = x + 800

Hence, x = 1200 m

The length of the bridge is 1200 m
