@zbr121115 本蒟蒻又改了一下现在80分

#include<bits/stdc++.h>
using namespace std;
int main()
{
    ios::sync_with_stdio(false);
    cin.tie(NULL);
    cout.tie(NULL);
    int s,v,c,t1,t,o;
    cin>>s>>v;
    if (v>=s){
        c=11;
    }else if (s%v!=0){
        c=s/v+1+10;
    }else{
        c=s/v+10;
    }
    t=c%1440;
    if (t>=480){
        t=1440-(t-480);
        if (t/60<10){
            cout<<"0"<<t/60<<":"<<t%60;
        }else{
            cout<<t/60<<":"<<t%60;
        }
    }else{
        t=480-t;
        if (t/60<10){
            cout<<"0"<<t/60<<":"<<t%60;
        }else{
            cout<<t/60<<":"<<t%60;
        }
    }
    return 0;
}
