Question 102801: A red candle is 45 cm tall and burns 3 cm per hour, a white candle is 30 cm tall and burns 1-1/2 cm per hour, how tall will each candle be after 1 hour, 3 hours, 5 hours and 12 hours?
What is the formula for calculating each candle's height at each time and which candle lasts longer? Will the red and white candles ever be the same height at the same time if started at the same time?
Please explain.
THANK YOU SO MUCH!

Question 105202: In rectangle ABDF, C and E are midpoints of sides BD and DF, respectively. This is actually a multi-step problem but the only question I have for this is how do you find the length of the midpoints? I'm pretty sure I can do the rest from there because I remember the rest of the steps, I'm just a little fuzzy on that part.

Question 106443: Red candle: 45 cm tall and burns 3cm per hour
White candle: 30 cm tall and burns 1 1/2 cm per hour.
How tall will each candle be after 1 hour?
How tall will each candle be after 3 hours?
How tall will each candle be after 12 hours?
Can you generalize-a formula- a system for calculating the candle's height at any given time?
Which candle will last longer? How do you know?
If you burn both candles continously (same start time) will they ever be the same height at the same time?
