```cpp
#include <bits/stdc++.h>
using namespace std;
int main() {
int s, v;
cin>>s>>v;
int t = ceil(s * 1.0 / v);
t += 10;
if(t <= 8 * 60) {
int h = 8 - t / 60 - 1, m = 60 - t % 60;
printf("%02d:%02d", h, m);
} else {
int h = 24 - (t / 60 - 8) - 1, m = 60 - t % 60;
printf("%02d:%02d", h, m);
}
return 0;
}
```
可以先参考
