Example 1: 180 meter and 120 meter mail train are running on parallel in a opposite direction at the speed of 67 km/hr and 77 km/hr respectively. Find when they cross each other ?
Answer : ( 67 + 77 )x 5 / 18 = 180 + 120 / Time
Time = 15 / 2 seconds.



Example 2: 170 meter and 130 meter long two super fast train are running in opposite direction at speed of 52 km/hr and 56 km/hr in par-allay. In What time would be they cross each other ?
Answer : Convert speed km/hr to m/sec = 52 + 56 = 108 x 5 / 18 = 30 m/sec.
Time = distance / speed = 170 + 130 / 30 = 300 / 30 = 10 sec.
So, they cross each other after 10 seconds.



Example 3:
A passenger train 330 meter long, Which is running at a speed of 60 Km / hr. In what time will it pass a man who is running at a speed 6 Km / hr in the opposite direction. In which the train is moving.
Answer: If direction is given in the opposite direction then we add both speed that is ( 60 + 6 ) =  66 Km / hr.
and now convert it into m / sec using 66 x 5 / 18 = 55 / 3 m / sec.
If the train time taken to passing a man who running in opposite direction, that is 55 / 3 m /sec. So we can easily get the distance of m / sec so it cover 330 meter that is = 330 x 3 / 55 = 18 sec.



Example 4:
Two super fast train 180 meters and 180 meters in length respectively are running in opposite directions, one at the rate of 58 km and the other at the rate of 50 km an hours. What time will they be completely clear of each other from the moment they meet ?
Answer :
Two fast trains are running is opposite direction and their relative speed is = 58+50 = 108 km / hours.
So the two trains are each other meet at 108 km /hours.
108 x 5 / 18 =  30 m / sec.
So, the required time  is = Total length / Relative speed = 180 + 180 / 30 = 12 secs.

Note: direction is given in the opposite direction then we add both speed
