You can put this solution on YOUR website! The temperature inside Daphne's refrigerator was 10 degrees at 1:00PM. If the temperature then started decreasing at a rate of one half of a degree per minute, what was the temperature at 2:20PM? Also what would be the temperature 6 hours after 2:20PM?
------------
From 1:00 to 2:20 is 80 minutes
80*0.5 = 40 deg decrease
10 - 40 = -30 degs
===============
6 more hours = 360 minutes
360*0.5 = 180 deg decrease
-30 - 180 = -210 degrees
That's a cold refrigerator.
