Graph A matches description 2 because the distance increases at a steady rate over time, indicating constant speed.
Graph B matches description 4 because the distance decreases over time, meaning the car is moving back toward the starting point.
Graph C matches description 1 because the distance remains unchanged as time passes, showing the car is not moving.
Graph D matches description 3 because the curve flattens over time, meaning the car covers less distance per unit of time, indicating decreasing speed.
