Final answer:
To produce 3,700 units of bread per hour, an oven needs to be able to bake at least 1164 units simultaneously.
Step-by-step explanation:
To find out how large an oven is required to produce 3,700 units of bread per hour, we need to calculate the number of units that can be baked simultaneously in 60 minutes.
Since it takes 19 minutes to bake one unit of bread, we can use the formula: Number of units baked simultaneously = Total units produced per hour / Time taken to bake one unit
Number of units baked simultaneously = 3700 / (60 / 19) = 1163.33 (approximately)
Therefore, the oven needs to be able to bake at least 1164 units of bread simultaneously.
