A thermometer graduated according to a linear scale reads a value \( x_{0} \) when in contact with boiling water and \( \frac{x_{0}}{3} \) when in contact with ice. What is the temperature of an object in \( { }^{\circ} \mathrm{C} \). If this thermometer in the contact with the object reads \( \frac{x_{0}}{2} \)
