As he approaches the parking lot of a market, he notices that the angle of depression from his balloon to a friend's car in the parking lot is 35. A minute and a half later, after flying directly over this friend's car, he looks back to see his friend getting into the car and observes the angle of depression to be 36. At that time, what is the distance between him and his friend? (Round to the nearest foot.)
