A car travels at a constant speed. The relationship between the car's odometer reading, $O$ , in miles, and the number of hours it has been driven, $h$ , is represented by the equation $O - 55 h = 25000$ . If the car travels at a constant speed of 55 miles per hour, what was the odometer reading, in miles, before the car started this trip?
