Answer:0.0922 Fahrenheit per minute
Explanation: Temperature change in degree Fahrenheit from Celsius is given by multiplying the change in temperature in celsius by 1.8 and adding 32 to it. Now the temperature you added is in Fahrenheit. But the temperature change is for a day. To convert change in temperature per day to per minute divide the obtained answer in Fahrenheit by 24*60.
Thus,
change in temperature in Fahrenheit: (56*1.8)+32= 132.8 degree Fahrenheit
change in temperature per minute: (132.8)/(24*60)= 0.0922 degree Fahrenheit per minute
