@lvjie14

#include <bits/stdc++.h>
using namespace std;
int s, v, t;
int main(){
    scanf("%d%d", &s, &v);
    t = 480 - (s + v - 1) / v - 10;
    if(t < 0) t += 1440;
    printf("%02d:%02d", t / 60, t % 60);
    return 0;
}

另外，这怎么多了个%？

scanf("%d%d%", &s, &v);

你的WA绝对是格式化输入的锅

还有：用于调试的代码为何不注释

@Lisuyang 大意了，提交答案的时候忘了删掉。
