  2. At what time (approximately) did Leslie pass Gale?

  3. About how far had Leslie traveled when she passed Gale?

  4. What do you think happened to Gale between 1:30 and 3:00?

  5. If Leslie continues at a steady pace, when will she complete the race?


Find the intersection point on the graph.
The lines represent the distance and time of the riders.
