Avg difficulty 2.5

Use this scenario: A turkey is taken out of the oven with an internal temperature of $\text{165}°\text{F}$ and is allowed to cool in a $\text{75}°\text{F}$ room. After half an hour, the internal temperature of the turkey is $\text{145}°\text{F} .$

To the nearest minute, how long will it take the turkey to cool to $\text{110}°\textrm{ }\text{F}?$
