Draw a distance-time graph of
the following scenario:
Martin gets in his car and
speeds up to 60 mph. He then
gets on the highway and
maintains a constant speed until
he reaches his exit. As he exits
the highway, he slows down and
stops at the red light.

Practice #7
Draw a distance-time graph and velocity-time
graph of the following scenario:
Jeremy
is standing outside. He begins to run
and reaches a speed of 10 mph. He keeps
running at this speed for 1 hour and slows
down to 5 mph. After another hour, he stops to
catch his breath.

Practice #8
Draw a distance-time graph and velocity-time
graph of the following scenario:
Kiara
steps out of her car and speeds up to a fast
walking pace. She maintains this speed as she
walks down the road. As she approaches a
crosswalk, she slows down to a stop and waits for
the light. Kira realizes that at this pace she will be
late. She begins to run down the street and soon
reaches her office building.
