Answer 1

Answer:

C 250

Step-by-step explanation:

Let the length of bridge be X meters

length of train = 50 meters

velocity of train = 30 km/hr

30 km / hr = 25/3 m/s

time taken to cross the bridge = 36 seconds

distance covered = x + 50 meters

distance =speed / time

x+50 =25X36/3

therefore. X +50 = 300

X which is length of bridge is 250 meters
