The question is gym is 8km away from where? His home or the gym.

As far as I can tell this is not a GRE Question. GRE Questions are not this poorly worded.

'From there' is not necessarily the anchor point for the distance of the gym.
For example: From there(i.e. tennis club) on he went to gym 8 kms away. / From there on he went to gym 8 kms away (from his home).

Either way the answer can be 23 or 7 depending upon his direction of motion
