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

33.3m^2

Explanation:

If Jessica waxes 20 m^2 of the floor in 3/5 of an hour, then;

20m^2 = 3/5 hr

To get the area that she waxes in an hour

x = 1 hr

Divide both expression

20/x = 3/5

3x = 20 * 5

3x = 100

x =100/3

x = 33.3m^2

Hence she can wax 33.3m^2 in an hour
