can you help me to answer question a and b?

[a] A patient of mass X kilograms is spiking a fever of 105 degrees F. It is imperative to reduce the fever immediately back down to 98.6 degrees F, so the patient is immersed in an ice bath. How much ice must melt for this temperature reduction to be achieved? Use reasonable estimates of the patient's heat capacity, and the value of latent heat for ice that is given in the OpenStax College Physics textbook. Remember, convert temperature from Fahrenheit to Celsius or Kelvin. [b] The patient's fever, it turns out, is being caused by the patient's own body generating too much heat over a long period of time. If the patient will produce W joules of excess heat each minute for 12 full hours before the fever breaks, how much ice must melt in order to keep the patient's body temperature steady that entire time
