Therefore, at 5 am, his command vehicle is still 64 kilometers away from the starting point;
(2) The distance after the first exercise is six or five kilometers, the distance after the second exercise is six or six kilometers, and the distance after the third exercise is six or eight kilometers.
The distance after the fourth exercise is 65 kilometers, the distance after the first exercise is 25 kilometers and the distance after the sixth exercise is 24 kilometers.
The distance after the seventh exercise is 22 kilometers, the distance after the eighth exercise is 6.4 kilometers, and the distance after the ninth exercise is 6.8 kilometers.
The distance after the tenth exercise is 28 kilometers, and the distance after the eleventh exercise is 6.4 kilometers;
So from 2 am to 4: 05 am, when he was farthest from the starting point, it was 68 kilometers.
