The rates are in units of square feet per hour.
Let r be the rate for 1 man.

RT=A for rate time area.

, the first sentence.

unknown number of hours t:
, the question, second sentence.

This is a Uniform Rates problem, and does not involve any quadratic equation. The second equation, although contains a term of , is still not quadratic.

Be sure you study the discussion given and understand it. Once done, the first equation lets you solve for r, and then substitute for r in the second equation, and solve that one for t.
