Thank you for the opportunity to help you with your question!

T(0)= 70+C = 200 

c= 130

T = 70+130*exp(-kt)

T(3) = 70+130*exp(-3k) = 180

exp(-3k) = 110/130 = 11/13

k = - ln(11/13)/3 =  0.05568

T(t) = 70+130exp(-kt) = 120 

exp(-kt) = 5/13

t = 17.2 minutes


Please let me know if you need any clarification. I'm always happy to answer your questions.
