    $\begingroup$ @satya Unless you show your attempts on solving the problem. Also, you question is not exactly on mathematics... $\endgroup$ – PierreCarre 2 days ago

    $\begingroup$ Surely, you understand that the problem, as it currently stands, is incomplete. We don't know what the cooling mechanism is, is there some cooling machine, what the ambient conditions are etc ... If we're on the North Pole, the process would be faster than in Africa. $\endgroup$ – Matti P. 2 days ago
