Let be the speed of train A, and let's set the origin in the initial position of train A. The equations of motion are
where are the positions of trains A and B respectively, and t is the time in hours.
The two trains meet if and only if , and we know that this happens after two hours, i.e. at
Solving this equation for v we have
So, train A is travelling at 105 km/h. This implies that train B travels at
Y + 2 = -(x - 4)
They point that they chose to identify for point-slope form was (4, -2)
The line slopes downward so the slope is -1
~~hope this helps~~
