The scones bake for 15 minutes, the minutes, the muffins bake for 12 minutes, and the cookies bake for 10 minutes. What one tray is done, he removes it and replaces it wit another tray of the same item.
How many minutes after Caylan puts the tray in the oven will he first remove the scones, muffins and cookie at same time?
? minutes
60 minutes
Since the scones take the longest to bake at 15 minutes, Caylan will first remove the scones after they have been in the oven for 15 minutes. However, he will only remove the scones when all three trays (scones, muffins, and cookies) are done baking at the same time. After removing the scones, he will continue to bake the muffins and cookies for an additional 45 minutes (15 minutes for scones + 30 minutes for the muffins to finish baking). Therefore, 15 minutes after putting the trays in the oven, Caylan will remove the scones, muffins, and cookies at the same time.
