Two work crews, crew A and Crew B, start digging a 300-foot tunnel through a mountain, but working toward each other from opposite sides. If Crew A digs at a rate of 12 feet a day and Crew B digs at a rate of 18 feet a day, how many feet will crew A have dug when the two crews meet?

I got 120 Feet for the answer. But the answer is 180 feet!? Is it a mistake? Because I think the answer 180 feet is for crew B.
