Question

Elio makes candles that are 14 cm tall.
Each candle burns 8 hours before going
out. He is wondering how many hours a
21 cm tall candle can burn for.
He assumes that the relationship between
the height of a candle and number of hours
it burns (h) is proportional.
How long can a 21 cm tall candle burn for?​
