Steve prepared a mango smoothie in which he churned the mixture at a temperature of 158∘F. He kept the mixture in the blast freezer, and after 15 minutes, the temperature was reduced to −7∘. What was the average rate at which the temperature of the smoothie dropped per minute?
Q. Steve prepared a mango smoothie in which he churned the mixture at a temperature of 158∘F. He kept the mixture in the blast freezer, and after 15 minutes, the temperature was reduced to −7∘. What was the average rate at which the temperature of the smoothie dropped per minute?
Calculate total change: Calculate the total change in temperature from 158°F to −7°F.Total change = Initial temperature - Final temperatureTotal change = 158−(−7)=165°F
Determine time span: Determine the time over which the temperature change occurred.Time = 15 minutes
Calculate average rate: Calculate the average rate of temperature change per minute.Average rate =TimeTotal change in temperatureAverage rate =15165=11∘F per minute
