Answer 1

Hello, Hannah,

We know that Nacny squeezes lemons at a rate of 32oz/20min. We want her rate in oz/hr, so use a conversion factor: 60min/1hr.

(32oz/20min)*(60min/1hr) =

= 96 oz/hr

Make use of units in problems - they make calculation a lot easier to understand, and it is fun canceling them out, where possible.

Answer 2

Need to convert per minutes to per hours. So every 20 minutes she squeezes 32 oz. That means in one hour she can squeeze 3 times the amount she did in 20 minutes since there are 60 minutes in one hour.
