改变代码如下
```cpp
#include <bits/stdc++.h>
using namespace std;
int main() {
int s, v, h = 8, m = 60, ht, mt;
cin >> s >> v;
if (s % v == 0) {
mt = s / v + 10;
} else {
mt = s / v + 11;
}
ht = mt / 60;
mt %= 60;
if (mt == 0) {
m = 0;
} else {
h--;
m -= mt;
}
if (ht >= 8) {
h += 24;
}
h = h - ht;
printf("%.2d", h);
cout << ":";
printf("%.2d", m);
return 0;
}
```
