[tex]x(t)=vt+x_0[/tex],

where [itex]x(t)[/itex] is the displacement, [itex]v[/itex] is the velocity, [itex]t[/itex] is the time, and [itex]x_0[/itex] is the initial displacement. To find out when the runners meet, simply equate the two functions and solve for time.

What is their relative velocity?

Dividing the distance by the velocity you find the time they take to cross each other.
