Two trains are running in opposite directions with the same speed.
Two trains are running in opposite directions with the same speed. If the length of each train is 80 m and they cross each other in 12 sec, then the speed of each train is?
Answer/Solution
24
Steps/Work
Let the speed of each train be x m/sec.
Then, relative speed of the two trains = 2x m/sec.
So, 2x = (80 + 80)/12 => x = 6.66
Speed of each train = 10 m/sec.
= 6.66 * 18/5 = 24 km/hr.
Answer: Option A
Then, relative speed of the two trains = 2x m/sec.
So, 2x = (80 + 80)/12 => x = 6.66
Speed of each train = 10 m/sec.
= 6.66 * 18/5 = 24 km/hr.
Answer: Option A
