Question

if the temperature at 9:00 pm was 12 degrees farenheit,and after 6 hours the temperature dropped to 6 degrees Fahrenheit below 0,what was the rate of change in temperature per hour?

Answer 1

The rate of change is it drops 3 degrees every hour.
my work :12-(3×6)=-6
9:00 = 12 degrees 10:00 = 9 degress. 11:00 = 6 degress. 12:00 = 3 degress 1:00 = 0 degress. 2:00 = -3 degress 3:00 = -6 degress
