a kick returner in a football game runs a constant 5.24 m/s toward the goal line, which d= 50.0 m away. at the instant shown, a tackler is 11.2 behind him, chasing at a constant 6.49 m/s.

How far from the goal line is he tackled?

When is he tackled?

k goes x yards
t goes (x+11.2) yards
both in time t
so
(x+11.2) = 6.49 t
x = 5.24 t
so
x/5.24 = (x+11.2)/6.49
