please i need help as have been trying to solve this question: A body cools from 70°C to 50°C in 6mins when the temp of the surrounding is 30°C. what wil be the tempt of the body after another 12mins if the cooling obeys newtons law of cooling

equation:

dq/dt = -k(θ-θs)

where m- mass of the body

c-specific heat capacity of the body

θ-temp of the body

θs-temp of the surrounding or room

3. The attempt at a solution

i tried sovling it as follows:

dq=mc(70-50)

=20mc

dq/dt= 20mc/6= -k(70-50) =-20k

dq=mc(50-θs)

dq-dt=mc(50-θs)/12=-k

got lost from here please help!!!!!
