Answer:
You look at the numbers
Step-by-step explanation:
1/8inch per hour
Step-by-step explanation:
The first thing we must observe is that the hourly rate for each candle is:
<em />
<em>scented candles:
</em>
(1/12) / (20/60)
Simplifying:
= (1/12) / (10/30)
= (1/12) / (5/15)
= (1/12) / (1/3)
= (3/12)
= (1/4) inches / hour
<em>Unscented candles:
</em>
(1/6) / (30/60)
Simplifying:
= (1/6) / (15/30)
= (1/6) / (3/6)
= (1/6) / (1/2)
= (2/6)
= (1/3) inches / hour
Answer:
The unscented candles burn faster at a rate of:
(1/3) inches / hour.
