In a historical movie, two knights on horseback start from rest 60 m apart and ride directly toward each other to do battle. Sir George's acceleration has a magnitude of 0.20 m/s2, while Sir Alfred's has a magnitude of 0.28 m/s2. Relative to Sir George's starting point, where do the knights collide?

They travel for the same time before colliding, so the distances covered before colliding are in a 0.28/0.20 = 1.4 ratio, if they maintain constant acceleration.
Alfred travels (1.4/2.4)* 60 = 35 m and George travels 25 m.
