Mr Wong drove 5N, 6E, 2S, and 1E. Putting that together, he ended up at the same place as if he had driven (5N + 2S) = 3N and also (6E + 1 E) = 7E. Draw a right triangle with legs of length 3 and 7 and calculate the length of the hypotenuse. As the crow flies, that is how far Mr Wong is from his house when he goes to the library. I don't know if that will help in finding the number of blocks east Mr Wong is from his house.
