Two train having the ratio of their speed 5 : 8 are running in opposite direction along parallel track. If each takes 10 seconds to cross an electric pole separately. In what time will they cross each other completely?



A 5 seconds
B 10 seconds
C 15 seconds
D 20 seconds
E None of these

Ans. B

Let speed of train be 5x and 8x

Relative speed = 5x + 8x = 13x

Now, length of train’s are 5x ×10 = 50x and 80 x meter

So, Required time = 130x / 13x = 10 sec
