Answer:
(A) 5:12
Step-by-step explanation:
Let's consider length of train A = x
then according to question length of train B = 3x
Since, train A takes 40 seconds to cross the pole, hence, the speed of train A
and since, train B takes 50 seconds to cross the pole hence the speed of train B
So, the ratio of speed of train A and B is given by
So, the ratio of speed of train A and B will be 5:12.
