Question

enny lit a 16-inch candle and a 12-inch candle at the same time. The 16-inch candle melted at a rate of 0.40 of an inch per hour while the 12-inch candle melted at a rate of 0.65 of an inch per hour. Write an equation that can be used to find h, the number of hours it would take before the two candles were the same height.

Answer 1

The two candles would be the same height after 16 hours.

Step-by-step explanation:

To find the number of hours it would take before the two candles were the same height, we can set up an equation using the given information:

Let h = number of hours

16 - 0.40h = 12 - 0.65h

We can solve this equation to find the value of h:

16 - 12 = 0.65h - 0.40h

4 = 0.25h

h = 16

So it would take 16 hours before the two candles were the same height.
