I don't know if you have thought about such a problem when lighting mosquito coils. How long does the coiled mosquito coil burn? Below we will use mathematical methods to calculate. You can take a look.
How long can a mosquito coil burn? This question is very simple. Just sit with a mosquito coil and wait for it. Is it OK to burn it? I can change it and think about how long I have to wait. If I know how long the mosquito coils are, and then know how long it takes to burn in a minute, then I can figure out how long it takes to burn, but the mosquito coils are curved and round. Xiaobian thinks of using the formula of the circumference of the circle, so many rounds, each must have a radius, too much trouble, hehe! If it is straight, it would be fine. Suddenly think of a good way, use a string to put a little bit on the mosquito coils, circle until the end point, cut the string, and measure it with a ruler, the total length is 80 cm. Next, mark a 1 cm mark at the beginning of the mosquito coil and ignite the mosquito coil. I looked at the time and watched it burn slowly. When burning to the mark, 1 cm of mosquito coils burned for 3 minutes and 30 seconds, which is 3.5 minutes. Finally, I calculated that the mosquito coil was 80×3.5 minutes=280 minutes, which is 4 hours and 40 minutes.
After reading the above content, everyone knows how long the coiled mosquito coil can burn, and how to calculate it.
