A plate is removed from an oven at temperature of 50◦C and placed in a large room at 20◦C . After 5 minutes the temperature of the plate is 40◦C . How much longer will it take to reach 30◦ ?

So far I think I have only learnt about Newton's Law of Cooling, so if the answer could be relative to that formula that would be helpful in my understanding.
