Each square labeled A to Z and A1 to A20, represent the corner of an intersection. The lines between the squares represent a city block. The intersections and city blocks fall
under 3 categories.
Large blocks: A, B,F, H, N, Q, R, U, W, Y, A3, A5, A7, A9,
A11, A14, A17, A19
Small blocks: C, D, E, I. J, L,M, O, P, S, T, V, X, A1, A4,
A10, Z, A12, A15, A16, A18, A20
Mini blocks: G, K, A2, A6, A8, A13
The time it takes to travel from one city block to another is:
In a car: 4 minutes
On a bike: 6 minutes
On foot: 10 minutes
In a car: 3 minutes
On a bike: 5 minutes
On foot: 8 minutes

The shortest route would take a car through A – G – H – S, covering two large blocks and one mini block. This would take 10 minutes by car.
The shortest route from A to S is A – G – H – S, taking 6 minutes by car for the first 2 blocks and 10 minutes on foot for the last large block. Total time is 16 minutes.
The shortest route from U to R passing through Q is U – V – W – Q – R. Time to walk these blocks is 38 minutes. (A)
The shortest route from block Y to G, avoiding S, is Y – A1 – T – H – G. Time by car is 14 minutes.
The fastest route is Z – A2 – A4 – A6 – A8 – A7. Time by bike is 22 minutes, plus 2.5 minutes to fix the bike, for a total of
