Homework Equations
v=d/t
The Attempt at a Solution
VL=VR+2km/h
d=6km
tL1tR+4min
tL2=tR +2
VL= 6km / (2-4) = 3km/min which is OBVIOUSLY WRONG. I have tried numerous things for the past couple hours, but cant seem to figure it out/. Help?
Yes! If Richard is 4 minutes ahead of Lance, that means that 4 minutes ago, Richard was where Lance is now. So, during that 4 minutes, Richard covered a distance of [itex]V_R \times 4min[/tex]Correction?
I believe that the statement that Richard is 4 minutes ahead of Lance, is to mean that it took Richard 4 minutes to cover the distance currently between them.
Therefore [itex]6 - D_R = 4V_R[/tex] not [itex]6 - D_R = 4 V_{L1}[/tex]
