Question

Jessica is a custodian at Oracle arena. She waxes 20 mi squared of the floor 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

Answer:

At The given rate, the area of floor that Jessica can wax is 33.3 m²

Step-by-step explanation:

Given as :

The area of floor waxed = 20 square meters

The time taken to waxed 20 square meters floor = $\dfrac{3}{5}$ hours

Let The area of floor waxed per hour = A m²

Now, Applying unitary method

∵ In $\dfrac{3}{5}$ hours, The  area of floor waxed = 20 m²

∴ In 1 hour , The area of floor waxed = $\frac{20}{\frac{3}{5}}$ m²

I.e In 1 hour , The area of floor waxed = $\frac{20\times 5}{3}$m²

Or, In 1 hour , The area of floor waxed = $\dfrac{100}{3}$ = 33.3 m²

Or, In 1 hour The area of floor waxed = A =  33.3 m²

Hence, At The given rate, the area of floor that Jessica can wax is 33.3 m² Answer
