One day at 2:00 AM, the temperature was -9 F in Nome, Alaska. At 9:00 AM the temperature was 26 F. What was the average change in temperature in hours?

26 + 9 = 35 degrees

2 to 9 = 7 hours

Take it from there.
7/35 = .2
Average change = .2
Jeffrey is totally wrong. If the average change were 0.2, then in 7 hours the temperature would change 1.4 degrees.

Jeffrey -- don't mess other students up by posting something wrong.
