A roast turkey is taken from an oven when its temperature has reached 185°f and is placed on a table in a room where the temperature is 75°f. (round your answers to the nearest whole number.) (a) if the temperature of the turkey is 150°f after half an hour, what is the temperature after 50 minutes? t(50) = °f (b) when will the turkey have cooled to 100°?

Answer :

a. After 50 minutes, the turkey will be at 92 degrees f. 
b. After 43 minutes the turkey will be cooled to 100 degrees f. 

Using unitary method, turkey's temperature after 50 minutes is 126.67°. Also, it will take approximately 73 minutes for the turkey to cool down to 100°.

What is unitary method?

The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Reduction in temperature after 30 minutes = 185° - 150° = 35°

Reduction in temperature after 1 minute = 35/30 = 1.167°

Reduction in temperature after 50 minutes = 50 * 1.167 = 58.3°

Temperature after 50 minutes = 185° - 58.3° = 126.67°

Decrease in temperature when the turkey has cooled down to 100° = 185° - 100° = 85°

Time taken by the turkey to cool down 85° = 85/1.167 = 72.86 minutes
