对了，最后把s, u改成double，然后吧%d 改成了%lf还是70分

@youzimo 你参考一下

#include<bits/stdc++.h>
#define int long long
using namespace std;
double s,v;
int h=8,m=0;
signed main(){
    cin>>s>>v;
    int t=ceil(s/v*1.0)+10;
    int a=t/60,b=t%60;
    if(b!=0) h--,m=60-b;
    if(a>h) a-=h,h=24-a;
    else h-=a;
    cout<<h/10<<h%10<<':'<<m/10<<m%10;
    return 0;
}
