This graph shows the temperature of a room over time. how many °f does the temperature of the room increase by every 1 min? enter your answer in the box.

The room increases 0.5°F every minute

How?
in 10 minutes the room increased from 65° to 70°
that means in 5 minutes the room increased from 65° to 67.5°
that's a 2.5° increase and if you divide that by 5 your get how much it increases by 1 minute; which is 0.5°

The only number less than 8 that can equal 12 would be 6, 36 is the dividend
