A 6-inch candle burns down in 4 hours. Assuming the candles are the same thickness and make (that is, directly proportional), how long would it take a 421-inch candle to burn down?Answer: hours
Q. A 6-inch candle burns down in 4 hours. Assuming the candles are the same thickness and make (that is, directly proportional), how long would it take a 421-inch candle to burn down?Answer: hours
Given Information: We are given that a 6-inch candle burns down in 4 hours. We need to find out how long it would take for a 4.5-inch candle to burn down, assuming the burn rate is directly proportional to the length of the candle.
Calculate Burn Rate: First, let's establish the rate at which the 6-inch candle burns. We divide the length of the candle by the time it takes to burn down.Rate = Length / Time = 4 hours6 inches=1.5 inches/hour.
Find Time for 4.5-inch Candle: Now, we have a 4.5-inch candle. We want to find the time it takes to burn down at the same rate of 1.5 inches/hour.Time = Length / Rate = 4.5 inches / 1.5 inches/hour.
Final Calculation: Perform the division to find the time.Time = 1.5inches/hour4.5inches=3hours.
