Question

Abe purchased a second candle that is shorter with a wider diameter than the first candle. It is 8 inches in length, and this candle burns down at the rate of 2/5 inches per hour. How long can this candle burn before its length is zero inches?

Answer 1

Answer: The second candle can burn for 20 hours before its length is zero inches.

Explanation:

If the second candle is 8 inches in length and burns down at a rate of 2/5 inches per hour, we can use a simple formula to find how long it can burn before its length is zero inches:

Number of hours = Length ÷ Rate of burn

Number of hours = 8 inches ÷ (2/5 inches per hour)

Number of hours = 8 inches × (5/2) hours per inch

Number of hours = 20 hours

Therefore, the second candle can burn for 20 hours before its length is zero inches.
