Question 4
Candle A takes 3 hours to burn completely. A shorter candle B, with a larger diameter, takes 5 hours. They are lit at the same time and have equal heights 2 hours later. What was their initial height ratio A : B?
Practice assumption: each candle loses height at a constant rate until it burns out. The source leaves this usual candle-model assumption implicit. Enter a simplified ratio in the exact form a:b or a : b (one space on each side of the colon). Other written forms are unsupported by the offline exact-text check and remain ungraded pending manual review.
