Wanda started walking along a path 2 minutes (120 seconds) before dave. wanda walked at a constant rate of 5 feet per second. dave walked along the same path at a constant rate of 10 feet precession. graph the system of linear equations. if they continue walking at these rates, when will dave catch up to wanda?

First we write the kinematics equations:
 a
 v = a * t + vo
 r = a * (t ^ 2/2) + vo * t + ro
 For Wanda we have:
 a = 0
 v = 5
 r = 5 * t
 For Dave we have:
 v = 10
 r = 10 * (t-120)
 To solve the system of equations, we graph both functions and see where
they intersect.
 We have to intersect in the ordered pair:
 (t, r) = (240, 1200)
 answer
 If they continue walking at these rates, Dave catch up to Wanda in 240s (1200 ft)
