Best ResponseYou've already chosen the best response.0\[\sqrt((20  60)^2 + (80  20)^2)\] \[\sqrt((40)^2 + 60^2)\] \[\sqrt(1600 + 3600)\] \[\sqrt(5200)\]

Best ResponseYou've already chosen the best response.0And then \[\sqrt((20  85)^2 + (80  110)^2)\]?

Best ResponseYou've already chosen the best response.2Since 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.

Best ResponseYou've already chosen the best response.0And what type of information do you need to find the shortest distance? and how can you use a diagram to help you?
