1 Road From Village To Village Length A B 1.0 2 A F 0.6 3 B G 0.7 4 B F 1.2 5 D 0.8 6 F 1.4 7 G 0.5 8 D E 0.6 9 E F 1.4 Therefore TA = d(C.A) + = 2 + and TA' = d(C.F) + d(F.A) - so 2- TB= d(C.B) + = 1.2+ and TB' = d(C.F) + d(F.B) - = 2.6- & TC = d(C.C) + = and TB' = d(C.F) +d(F.C) - = 2.8- TD = d(C.D) +8 = 0.8 + and TD' = d(C.F) + d(F.D) - = 3.4- TE = d(C.E) +
