@Wangbingxiang 求关

#include<bits/stdc++.h>
using namespace std;
int main(){
    double s,v,t;
    cin>>s>>v;
    t=ceil(s/v)+10;//时间  s/v+额外花费10分钟
    int h=ceil(t/60);//小时 时间/60
    int m=(int)t%60;//分钟 时间%60
    printf("%02d:%02d"/*格式控制*/,(8-h+24)%24,(0-m+60)%60);
    //但是提前的时间不会超过'一天'。( (8-h+24)%24 )
    return 0;//好习惯不能忘。 
    //全剧终！ 
}
