A car travels along a straight east/west road. A coordinate system is established on the road, with x increasing to the east. The car ends up 25 mi rest of the origin, which is defined as the intersection with Mulberry Road. If the car's displacement was 74 mi, what was the position of the car at the start? Don't forget the units!
