The answer seems a bit too far out from 7 given by the book.
If they move 6 rows, they are 0.26 rows "short" - so you'd still be outside the limits.
6.26 is the MINIMUM amount they must move in fractional rows. But seats come in integer rows - unless on a certain recent flight from SFO.
So if you must move a bit more than six, the minimum you actually must move is seven.
