Answer:

2km

Explanation:

- Abby walked 3 km west: Abby is 3km west from her starting point.

- Then she walked twice as far going east: she walks 6km east so she's 3 km east from her starting point

- She continued east for another kilometre: She's is 4 km east from her starting point

- Stopping 2 km east of Lauren's home: She's currently 2 km east from Lauren's home and 4km east from her starting point. Therefore, Abby's starting point is 4km - 2km = 2km west from Lauren's home
