An ice pack was placed in a chiller set to -4 °C. The ice pack was originally at 37 °C and it cooled to 26 °C in 16 minutes. Assuming the rate of cooling is proportional to the temperature difference between the chiller and the ice pack, calculate:
a) The temperature after 60 minutes
b) The time to cool within 1°C of the chiller temperature
