Answer :
Answer:[tex]\dfrac{100}{3}m^{2}[/tex]
Step-by-step explanation:
Let [tex]r[/tex] be the rate at which Jessica waxes.
Let [tex]A[/tex] be the area which Jessica waxes in [tex]t[/tex] hours of time.
So,[tex]A=rt[/tex]
Given that she waxes [tex]20m^{2}[/tex] in [tex]\frac{3}{5}[/tex] hours.
[tex]20=r\times \frac{3}{5}[/tex]
[tex]r=\frac{100}{3}[/tex]
To know how much area she sweeps in a hour,substitute [tex]1[/tex] for [tex]t[/tex] in the above equation.
[tex]A=\frac{100}{3}\times 1=\frac{100}{3}m^{2}[/tex]
