2) Bill started walking to town at a speed of 6km/hr. Thirty minutes later Sue wanted to catch up to Bill and started running at 12 km/hr. Draw a graph to show how long it would take for Sue to catch up to Bill.
-
6km/hr(t) = 12km/hr(t - 0.5)
6t = 12t - 6
6 = 6t
t = 6/6 = 1 hour
Plot both sides of the first equation, they should intersect at t = 1.

6t = 12t - 6
6 = 6t
t = 6/6 = 1 hour
Plot both sides of the first equation, they should intersect at t = 1.
