Question

Jessica is a custodian at Oracle Arena. She waxes 20 m2 of the floor in 3/5 of an hour. Jessica waxes the floor at a constant rate. At this rate, how many square meters can she wax per hour?

Answer 1

to solve this, you need to set up an equation to solve for x, the number of square meters waxed in an hour:

`(20)/(3/5) = (x )/(1 )`

you can use cross multiplication to solve for x:

`(3)/(5) x = 20`

`3x = 100\\x = 100/3`

so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.
