Question

Two trains of equal speed are running in opposite directions. If their lengths are 120 metres and 140 metres and they cross each other in 10 sec, then find the speed of each train.

• A. 13 m/s
• B. 10 m/s
• C. 16 m/s
• D. 14 m/s

Answer 1

Answer:

A. 13 m/s

relative speed = speed of train1+ speed of train2 = 2S speed =(120+140)/10=260/10=26 m/s 2S=26 S=13 m/s
