#include <bits/stdc++.h>
using namespace std;

int main() {
    int s, v;
    cin>>s>>v;
    int t = ceil(s * 1.0 / v);
    t += 10; 
    if(t <= 8 * 60) {
        int h = 8 - t / 60 - 1, m = 60 - t % 60;
        printf("%02d:%02d", h, m);
    } else {
        int h = 24 - (t / 60 - 8) - 1, m = 60 - t % 60;
        printf("%02d:%02d", h, m);
    }
    return 0;
}

可以先参考
