A taxi has three passengers when it starts at A. It must drop off two people at B and a third at C. The arrows represent one-way streets. Also, travelling north takes 12 mins per block, travelling south takes 5 mins per block, travelling west takes 6 mins per block and travelling either southwest or northeast takes 10 mins per block. If the taxi charges $0.50/block and the time charges are 0.10/min, what is the cheapest route from A to C? How should each passenger pay? Keep in mind that the vector directions must be obeyed (therefore you cannot simply go only northeast as the southwest vectors would direct you in the opposite direction).
