it asks at time 5 which instantaneous velocity is greater

A velocity time graph starts from 0-5 s , object A has constant velocity of 4 m/s. Object B has an initial velocity of 8 m/s and constantly decreases and reaches 0 m/s at 5 s. so i need to know what is the instantaneous velocity. Also, which of the object's instantaneous velocity is greater...
