Solution
One candle burns at the rate of 10in/5hr or 2 in/hr so if t ismeasured in hours the length the
candle left is d=10-2t. Forcandle number 2 it burns at 10/4=5/2 in/hr so the legnth of thecandle
left is e=10-(5/2)t. So the length of the first candled is 3 times the length of the second candle e,
sod=3e. So 10-2t=30-(15/2)t, so -20=(4/2)t- (15/2)tso -20=-(11/2)t
Thus 40=11t so t=40/11 hrs. (or about 3.64 hrs)
