hoa [83]

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.
