Solve the applied problem.

Anne is standing on a straight road and wants to reach her helicopter, which is located 2 miles down the road from her, a mile from the road in a field (see the figure). She can run 5 miles per hour on the road and 3 miles per hour in the field. She plans to run down the road, then cut diagonally across the field to reach the helicopter. If she runs less than a mile on the road and arrives at the helicopter in 42 minutes (.7 hour), exactly how far did she run on the road?
