这是我的代码

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int s,v,t,a,h,m;
    cin>>s>>v;
    t=ceil(s*1.0/v);
    a=(480+2880-10-t)%1440;
    h=a/60;
    m=a%60;
    if(h<10)
    cout<<0;
    cout<<h<<":";
    if(m<10)
    cout<<0;
    cout<<m;
 }

    m+=10;
    m=8*60-m;
        m=m+24*60;
        m%=1440;

        }
        else{

    }
    else{

        }
    }
    return 0;
}

首先，你的m与h搞反了。其次，你的m要向上取整。再次，m要模24*60，这样如果m大于一天就可以减去一天。
