If it takes five minutes to boil one egg, how long will it take to boil four…

Answer: Five minutes.

Explanation: If eggs are boiled together in the same pot with enough water and the heat source is sufficient, they cook at the same time. Therefore four eggs boiled simultaneously will take about the same five minutes as one egg.

• Assumption: The pot is large enough so the eggs are not overcrowded and the water can return to boiling quickly.

• Practical note: If many eggs are added to cold water or the heat is insufficient, it may take slightly longer for the water to come back to a boil.
