@[Wangbingxiang](/user/889828) 求关
```cpp
#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！
}
```
