How much time does it take to boil an egg?

The time it takes to boil an egg depends on the desired doneness and the starting temperature of the egg. For a soft-boiled egg with a runny yolk, it typically takes about 4-5 minutes. For a medium-boiled egg with a slightly firmer yolk, it usually takes around 7-8 minutes. For a hard-boiled egg with a fully cooked yolk, it can take about 9-12 minutes. It's important to adjust the cooking time based on personal preference and the size of the egg.
