The third team scored seven points, and there was a draw, so there were six points left in three games. According to the relationship between victory and defeat, it can only be 2 wins, 1 negative (because it takes 6 points, it can't be 6 if there is a draw).

therefore

Now, if the fifth place wants to score the most points, let's see if the fourth place can get 6 points (obviously 2 wins and 2 losses), then the fifth place can get 5 points at most (1 wins and 2 draws 1 negative).

(Can't exceed 5 points. Suppose he scored 6 points, the fourth place scored 7 points, and the fourth place scored the same as the third place, which did not meet the question. )

The fifth place is at least 1 point, that is, the sixth place (the last place has not won a game) and the fifth place (0 wins 1 draw and 3 losses).

If you have studied equations:

The fastest arrival is two pairs arriving at the same time.

B got on the bus for the first time at T 1, a first time at 1.25VT 1, and the second time at 10VT 1.

It takes T210vt1-1.25vt1= (1.25+10) vt2 to get back to armor.

The time for Party A and Party B to arrive at the park together is t310vt3-vt3 =10vt1+vt2-1.25 (vt1+vt2).

Distance ratio:1.25v (t1+t2): v (t2+t3) = 9: 7.
