Sketch a graph of the car's speed vs. time. (c) Since the speed is no longer constant, it is much harder to calculate the distance traveled. But we can still try. Suppose we wanted to calculate how far the car went in the sin minute from 1:00 and 1:01. i. Let's pretend that the car's speed is constant for this single minute. What might be a reasonable approximation for the car's speed, in this scenario? (There is no one single correct answer to this question; make your best estimate.) ii. Under this assumption, approximately how far did the car go during this minute?
