• A. (45/4) seconds
• B. (47/4) seconds
• C. 20 seconds
• D. 16 seconds

Answer 1

Answer:

A. (45/4) seconds

Solution: Given Length of train = 330 meters The train crosses a 550 meters long bridge in 11 seconds Formula used: Time = Distance/Speed Solution: Speed of train = (330 + 550)/11 = 880/11 Time taken to cross the second bridge = (330 + 570)/880 × 11 = (45/4) seconds Therefore, the train takes (45/4) the seconds to cross a 570 meters long bridge.
