Problema Solution
a candle that has been burning for 2 minutes is eight inches long same candle is 7 and three quarters long after burning 3 minutes assume that the candle will burn at this rate
Answer provided by our tutors
difference in the candle height:
8 - 7 3/4 = 1/4 inch
time difference in the measurements:
3 - 2 = 1 minute
7.75 / 0.25 = 31
the candle is burning at the rate of 1/4 inch per minute, so it will last approximately 31 minutes longer
