Question 1173574
.
<pre>

All you need to do is to take °C from each line (from its right end) and to divide this temperature change by 2040-2010 = 30 years.


For example:


Model A:  You take  1.4°C  from the Line A (from its right end) and divide it by 30.

          Thus you obtain the <U>ANSWER</U>  for the model A: it is  {{{1.4/30}}} degrees Celsius per year, or 0.0467°C per year.



Do the same for each of the remaining models B, C and D exactly as I instructed you with the model A.

It is of the 2 + 2 = 4 complexity level assignment.
