---------------
Their positions with the point of departure form a right triangle, which makes it easier.


s = 25t, t in hours, s in miles

Their distances travelled will be the legs of a right triangle.
The distance between them will be the hypotenuse.
rt=d
It will be multiple of the 3,4,5 triangle

25t=d
