@[YangXiao870803](/user/621423) 这是我的代码可以参考（
```c++
#include<iostream>
using namespace std;
double a,b,s;
int s1=470;
int main(){
cin>>a>>b;
s=a/b;
s1=int(s1-s);
if(s1>=0){
if(s1%60<10){
cout<<"0"<<s1/60<<':'<<"0"<<s1%60;
}
else cout<<"0"<<s1/60<<':'<<s1%60;
}
else{
s1=1440+480-10;
s1=int(s1-s);
if(s1%60<10){
cout<<s1/60<<':'<<"0"<<s1%60;
}
else cout<<s1/60<<':'<<s1%60;
}
}
```
