To solve this problem, we need to determine the time it takes for the train to completely cross the bridge. We can use the formula:
Time = Distance / Speed
Given:
Length of the train = 150 meters
Length of the bridge = 250 meters
Speed of the train = 144 km/hr
Converting the speed to meters per second:
Speed = 144 km/hr * (1000 m/km) / (3600 s/hr) = 40 m/s
Calculating the total distance the train needs to cover to cross both the train and the bridge:
Total distance = Length of the train + Length of the bridge = 150 m + 250 m = 400 m
Now, substituting the values into the time formula, we get:
Time = 400 m / 40 m/s = 10 seconds
Therefore, it takes the train 10 seconds to cross the entire bridge.
Hence, the correct answer is option D) 10 seconds.

Calculating the total distance the train needs to cover to cross both the train and the bridge:
Total distance = Length of the train + Length of the bridge = 150 m + 250 m = 400 m
Now, substituting the values into the time formula, we get:
Time = 400 m / 40 m/s = 10 seconds
Therefore, it takes the train 10 seconds to cross the entire bridge.
Hence, the correct answer is option D) 10 seconds.
