ANSWER

92 miles

Step-by-step explanation

Let us make a sketch to represent the problem:

From the diagram, A is the starting point, B is the point she met her grandmother and C is the point she met her friend.

To find how far she is from her starting point, we have to simply subtract AB from BC.

That is:

BC - AB

= 212 - 120

= 92 miles

That is how far she is from her starting position.
