the train tragedy

Algebra Level 1

Two trains start simultaneously from points A and B towards each other. Each of them first moves with uniform acceleration (the initial speeds of the trains is equal to zero , the accelerations are different ), and then , having attained a certain speed (at different time moments ), uniformly . the ratio of the speeds of the uniform motion of the trains is 4:3 . At the time of their meeting , The speeds of the trains were equal and they arrived at points A and B simultaneously . find the ratio of accelerations of the trains . Write the answer in the form (p/q) eg 4/3
