if train b, travels 8/7 as fast as train a. find the speed of each train
Answers: 2
be the speed of train A, and let's set the origin in the initial position of train A. The equations of motion are
are the positions of trains A and B respectively, and t is the time in hours.
, and we know that this happens after two hours, i.e. at
