If it takes bianca 30 minutes to bake 2 pans of brownies, how many pans of brownies can she bake in 7 hours?

Bianca can make 28 pans of brownies in 7 hours

Step-by-step explanation:

As we know, 1 hour = 60 minutes

so, 1/2 hour = 30 minutes

Bianca takes 1/2 hour to make pans of brownies = 2 pans

Bianca takes 1 hour to make pans of  brownies = 2 / (1/2) pans

Bianca takes 7 hour to make pans of  brownies = 4 * 7 pans

                                                                                = 28 pans

So, Bianca can make 28 pans of brownies in 7 hours.
