Answer:

-2 km

Step-by-step explanation:

first, as she travells towards right, so distance travelled is +1 Km.

Then as she comes back to home (by travelling to the left side) it is +1 -1 = 0, nothing but her home (as given in the Q)

Now she moves 2 km towards left, so

0-2 = -2

Therefore, she is -2 km away from her home
