The temperature, H, in degrees Celsius (degC), of a cup of coffee placed on the kitchen counter is given by H = f(t), where t is in minutes (min) since the coffee was put on the counter.

Suppose that and f(30) = 62. Fill in the blanks (including units where needed) and select the appropriate terms to complete the following statement about the temperature of the coffee in this case.

At 30 minutes after the coffee was put on the counter, its temperature is 62 degC and will decrease by about ________ in the next 75 seconds.

Include units for this problem.

|f'(30)| = 0.8
