The key idea is to match burn time with fuse length using the burn rate. To get a fuse that burns for a specific time, multiply how fast it burns by how long you want it to burn. In this context, the fuse burns at 0.3 inches per second. For a burn time of 90 seconds, the needed length is 90 × 0.3 = 27 inches, which is 2.25 feet. So the correct length is 2.25 feet. If your fuse has a different burn rate, you’d use the same formula with that rate and convert units as needed.
