The point of intersection between the height or elevation of Erik to that of Raj at a certain point in time, t is the distance in which they will meet. To determine this point, we get the value of h and t.
h = 12  0.75t
h = 0.75t
Substituting the expression for h in the second equation to the expression in the first equation,
h = 12  h
h = 6
Get value of t,
6 = 0.75t ; t = 8
Therefore, after 8 t's they will meet at an elevation of 6.
