At a rate of 14 pizzas per hour, how long will it take to make 840 pizzas?

To determine how long it will take to make 840 pizzas at a rate of 14 pizzas per hour, you can use the formula for time, which is total quantity divided by rate. Here, that means:

Time = Total Pizzas / Rate of Making Pizzas

Substituting the numbers into the formula:

Time = 840 pizzas / 14 pizzas per hour

When you calculate this, you divide 840 by 14:

840 ÷ 14 = 60

This means it will take 60 hours to make 840 pizzas at a rate of 14 pizzas per hour. Therefore, the correct answer is that it will take 60 hours.
