As an AI language model, I'm unable to view or interpret images or graphs directly. If you can describe the data or pattern present in the graph or provide more details, I can try to help you determine at what time Sharon stopped to buy gas during her trip.
I'm sorry, but I cannot see or access any graph provided. However, if you describe the data or provide additional details, I can try to help you determine at what time Sharon may have stopped to buy gas.
