Ruby is visiting san francisco. from her hotel she walks 4 blocks east and 2 blocks north to a coffee shop. then she walks 5 blocks west and 1 block north to a museum. where is the museum in relation to her hotel?

The museum is 1 block west and 3 blocks north from the hotel.

Step-by-step explanation:

First of all, Ruby goes Northeast to a coffe shop, walking 4 blocks to the east and 2 blocks to the north. Then, she goes 5 blocks to the west, and 1 block to the north.

Therefore, she walks:

-3 blocks north

-4 blocks east

-5 blocks west

As east and west are contrary, we have to substract the lower number to the higher one in order to know the difference between both directions (5 W - 4 E = 1 W). As a result, Ruby finally moved west by 1 block.

Finally, we know that the museum is 1 block west and 3 blocks north from the hotel.
