The information is incorrect as flow rate per minute of zero kg is stated. However, as the input energy is 960 watts the temperature rise would be 13.7 degrees Celsius per kg of water per minute.

Explanation:

The Heat equation would be as follows
Input energy per minute = #Pxxt=IVt=240xx4xx60=57,600# J
Temperature Rise per minute #(Delta theta)=57600/(mxx4200) #
Specific heat capacity of water = #4,200 Jkg^-1K^-1#
#(Delta theta)=13.7 ^oC#
