Mario rides his motorcycle in going to school. He drives at an average speed of 30 kilometers per hour. The distance between his house and the school is 15 kilometers. Every time he sees his best friend Jessica walking on the road, he invites her for a ride and lowers his speed. On the other hand, he increases his speed when he wakes up late for school.
a) If x represents the time it takes Mario to drive to school with the given distance of 15 kilometers, how will you represent the relationship of his speed (y) versus the time (x)?
4. A computer animator is trying to make an animation of a rabbit rushing back and forth along a
sidewalk. He decides to model the rabbit's velocity over time as shown in the following graph, where
time is measured in seconds and velocity is measured in meters per second.

(Here, positive velocities indicate that the rabbit is heading east; negative velocities indicate that the
rabbit is heading west.)
(a) Suppose the rabbit starts at a position we'll call 0. Sketch a rough graph of the rabbit's position
as a function of time on the interval [0, 10]. We do not expect your graph to be perfect, but it
should accurately show whether the graph is increasing or decreasing and whether it is concave
up or concave down.
(b) At time 0, there was a squirrel sitting 2 meters east of the rabbit. Suppose that the squirrel's
velocity on [0, 10] is given by the same graph shown above. On your graph from (a), also sketch
the squirrel's position as a…
