Calculating Rate of Heat Removal

A Carnot heat engine receives heat from a reservoir at 1700 degrees Farenheit at a rate of 700 Btu/min and rejects the waste heat to the ambient air at 80 degrees Farenheit. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at 20 degrees Farenheit and transfers it to the same ambient air at 80 degrees Farenheit. Determine:

a) the maximum rate of heat removal from the refrigerated space
b) the total rate of heat rejection to the ambient air

a) 4200 Btu/min
b) 4900 Btu/min

Please show steps. Thanks.
