( 1/2 acre ) / ( 4 days ) = (2 and 3/4 acre) / X or (2 and 3/4 acre) / ( ( 1/2 acre ) / ( 4 days ) ) = X or 2.75 / ( 0.5 / 4.0 ) = X = 22 Or think of it like this: If they can do 1/2 acre in 4 days, that's 1/8 acre is 1 day, 1/4 acre in 2 days. There are 11 quarter acres in 2 and 3/4 acres. 11 * 2 = 22 days (By the by, I'd look for a better crew, because these are very slow.)
