算了，直接帮你改了，AC代码

#include<bits/stdc++.h>
using namespace std;
int main()
{
    double s, v;
    cin >> s >> v;
    if (s >= 1 && v <= 1e4)
    {
        double time;
        int time2;
        time = s / v + 10;
        time2= 8 * 60 - ceil ( time );
        int HH, MM;
        if (time <= 480)
        {
            HH = time2 / 60;
            MM = time2 % 60;
        }
        else
        {
            time2+=1440;
            HH = time2 / 60;
            MM = time2 % 60;
        }
        printf("%02d:%02d", HH, MM);
    }
    system("pause");
    return 0;
}
