the largest temperature decline during a 1 day (24 hours) time period was 56 degrees Celsius in Browning, Montana. Express this as degrees Fahrenheit per minute

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
