Julie and Dale live in Gridtown. The streets running north/south are parallel with one another as are the streets running east/west. Every time that Julie and Dale walk, they record how far they have travelled. The distance between each block is 100 m. During their most recent walk around Gridtown, Julie and Dale left home and travelled 6 blocks north to the Fruit Market before turning right. Then they walked 4 blocks east to the Library . They turned right again and walked 3 blocks south to the Pet Store. Then they walked 2 more
blocks east to the park.

If they take the shortest route back home, how far will they have travelled in total?
