21. Burning String Duration How long must a string be in order for it to burn for 3 minutes and 30 seconds? Added 1 December 2011 Show Solution Solution: The length of the string depends on its material and thickness. However, if we assume a specific burn rate, we can calculate the required length. For example, if a string burns at a rate of 1 meter per minute, then to burn for 3 minutes and 30 seconds (which is 3.5 minutes), the string must be 3.5 meters long.
