Respuesta :

Answer:

45 cm long candle would take 18 hours to burn.

Step-by-step explanation:

Given:

Elton is a candle maker.

Each 15 cm long candle he makes burns evenly for 6 hours.

If Elton makes a 45 cm long candle.

Now, to find hours it would take to burn 45 cm long candle.

So, to solve by using unitary method:

Each 15cm candle take time to burn = 6 hours.

So, 1 cm candle take time to burn = [tex]\frac{6}{15}\ hour.[/tex]

Thus, 45 cm candle take time to burn = [tex]\frac{6}{15} \times 45\ hours[/tex]

[tex]\frac{6}{15}\times 45\\\\=0.4\times 45\\\\=18\ hours.[/tex]

Therefore, 45 cm long candle would take 18 hours to burn.
