Question 1048202
Given that a candle is 13.5 inches tall when it has been burning for 8 hours at a rate of 0.5 inches per hour, 
How tall was the candle when it had been burning for 2.5 hours?
---------------
It's 5.5 hours less burning time (8 - 2.5)
5.5*0.5 = 2.75 inches taller.
13.5 + 2.75 = 16.25 inches
