You and your two friends are on a road trip when your car runs out of gas on a rural road. You've called for roadside assistance, but they can't tell you exactly when they'll arrive - it could be anywhere from 30 minutes to 3 hours. Your friend Taylor suggests that all three of you should walk to the nearest gas station, which is about 3 kilometers away. Your other friend Jordan thinks you should all stay with the car and wait for assistance to arrive.
