When an object is shot from the bottom of a long smooth inclined plane kept at an angle \(60^\circ \) with horizontal, it can travel a distance \( {\text{x}_1} \) along the plane. But when the inclination is decreased to \(30^\circ \) and the same object is shot with the same velocity, it can travel \( {\text{x}_2} \) distance. Then \( {\text{x}_1}:{\text{x}_2} \) will be
