A train traveling at 80 km/h crosses another train traveling in the same direction at 26 km/h in 30 seconds. What is the combined length of both the trains?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 450 m.
Relative speed = 80 - 26 = 54 km/hr
⇒ 54 × 5/18 = 15 m/sec
Distance = speed × time
Distance = 15 × 30 = 450 meters
