A body cools in 10 minutes from \( 60^{\circ} \mathrm{C} \) to \( 40^{\circ} \mathrm{C} \). What is the temperature of the body after next 20 minutes?
\( \mathrm{P} \) The temperature of surroundings is \( 10^{\circ} \mathrm{C} \).
\( \mathrm{W} \)
(1) \( 14^{\circ} \mathrm{C} \)
(2) \( 30^{\circ} \mathrm{C} \)
(3) \( 20^{\circ} \mathrm{C} \)
(4) \( 14.36^{\circ} \mathrm{C} \)
