```
#include<bits/stdc++.h>
using namespace std;
int main(){
double s,v,hour,n,minute,g;
scanf("%d %d",&s,&v);
minute=ceil(s/v);//等价于你求i的值
minute=minute+10;
hour=floor(minute/60);
n=minute-hour*60.0;
if(n!=0){
n=60-n;
hour=8-1-hour;
if(hour<0)hour=24-abs(hour);
}
if(n==0){
hour=8-hour;
if(hour<0)hour=24-abs(hour);
}
if(hour>=10&&n>=10)cout<<hour<<":"<<n<<endl;
if(hour>=10&&n<10)cout<<hour<<":"<<"0"<<n<<endl;
if(hour<10&&n>=10)cout<<"0"<<hour<<":"<<n<<endl;
if(hour<10&&n<10)cout<<"0"<<hour<<":"<<"0"<<n<<endl;
return 0;
}
```
