In a historical movie, two knights on horseback start from rest 88.0m apart and ride directly toward each other to do battle. Sir George's acceleration has a magnitude of 0.300m/s (squared), While Sir Alfred's has a magnitude of 0.200m/s (squared). Relative to Sir George's starting point, where do the knights collide?

(1/2)(.3) t^2 + (1/2)(.2) t^2 = 88
find t
then
x = (1/2) (.3) t^2
