Two goods trains each 500 m long are running in opposite directions on parallel tracks.
Two goods trains each 500 m long are running in opposite directions on parallel tracks. Their speeds are 60 km/hr and 90 km/hr respectively. Find the time taken by the slower train to pass the driver of the faster one?
Answer/Solution
24
Steps/Work
Relative speed = 60 + 90 = 150 km/hr.
150 * 5/18 = 125/3 m/sec.
Distance covered = 500 + 500 = 1000 m.
Required time = 1000 * 3/125 = 24 sec.
Answer:C
150 * 5/18 = 125/3 m/sec.
Distance covered = 500 + 500 = 1000 m.
Required time = 1000 * 3/125 = 24 sec.
Answer:C
