Compare the distances TUV and TVU and take the shorter of the two.

\[\sqrt((20  60)^2 + (80  20)^2)\] \[\sqrt((40)^2 + 60^2)\] \[\sqrt(1600 + 3600)\] \[\sqrt(5200)\]

And then \[\sqrt((20  85)^2 + (80  110)^2)\]?

Since the route TUV and TVU both use UV, we know they are equal. So just compare which of TU or TV is shorter. one of them is sqrt(5200), and the other is sqrt(5125), so make your choice.
