Question

A tortoise and a hare are running in a race. You are asked to prepare graphs similar to those in your reading material to graph the progress of each animal during the race.As in the text, distance is the vertical scale of your graph and time is the horizontal scale. The tortoise keeps crawling at a constant rate without stopping. However, because the hare is so confident he will win, every once in a while he stops hopping and waits for the tortoise to almost catch up, then he starts hopping again. During the time that the hare is stopped, what is the slope of his line on your graph?

Answer 1

When stopped, the slope of the hare's x vs. t line is zero
