Question 815135: Bill started walking to town at a speed of 6 km/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. Draw the graph
Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
bill speed = 6km/h
bill distance = y
bill time = x
distance = rt
y=6x
-----------
Sue
distance =y
speed = 12 km/h
time = (x-1/2)
y= 6(x-1/2)
y=12x-6

generate points for both equations
and draw the lines
x value of the intersection point is the time she overtakes

x value is 1 hour
