Ms. Sperlak bakes 3 1/2 pies in 20 minutes. At this rate how many pies can she bake in 1 hour? 2 hours? (This is math)

she makes 4.5 pies in one hour and bakes 9 pies in 2 hours

Explanation:
First you find out how many times she makes a round of pies in one hour
60/20=3.

Then you multiply 3 1/2 by 3
3+1/2•3= 4.5

To find how many pies she bakes in 2 hours multiply 4.5•2=9

Not sure if this is correct it’s been a while since I’ve did this
