This motion map represents the movement of two animals. Examine the motion map. One animal is an antelope that is already running. The other is a cheetah that starts running after the antelope passes it. Does A or B represent the motion of the cheetah?

Assume the first dot for animal A represents t = 0. At which time does animal B overtake animal A?

t = seconds
