ANSWER:

Therefore in an hour she will have already painted 16 1/2 square meters

Explanation:

We can calculate the area that Rachel has painted by means of the following proportion:

But first we must convert the mixed number 5 1/2 to a fractional number


5(1)/(2)=(11)/(2)

Now yes, the proportion would be:


((11)/(2))/((1)/(3))=(x)/(1)

Solving for x:


\begin{gathered} (11\cdot3)/(2\cdot1)=(x)/(1) \\ x=(33)/(2) \\ (33)/(2)=16(1)/(2) \end{gathered}
