In what time will a 110 metre long train running at 20 meters/Sec cross a 132 metre long bridge?

• A. 9.8 seconds
• B. 12.1 seconds
• C. 14.3 seconds
• D. 12.42 seconds

Answer 1

Answer:

B. 12.1 seconds

⇒ Distance to be covered in order to cross the bridge = length of train + length of bridge = 132 + 110 = 242 m ⇒ Speed = 20 m/s ⇒ Time = 242/20 = 12.1 Seconds
