更新一下30分代码（笑）
```c
#include<bits/stdc++.h>
using namespace std;
int main()
{
int t,h,m;
double s,v,t1,t2;
cin>>s>>v;
t1=s/v;
t=t1;
t2=t;
if(t1>t2)
{
t+=1;
}
t+=10;
if(t<60)
{
if(60-t<10)
cout<<"07:0"<<60-t;
else
cout<<"07:"<<60-t;
}
else
if(60<=t<480)
{
if(t%60==0)
{
cout<<"0"<<8-t/60<<":00";
return 0;
}
h=t/60;
m=t-h*60;
cout<<8-m-1<<":"<<60-m;
}
else
{
if(t==480)
{
cout<<"00:00";
}
else
{
if(t%60==0)
{
h=t/60;
if(24-h<10)
{

}
else
{
cout<<24-h<<":00";
}
return 0;
}
h=t/60;
m=t-h*60;
h=h-8;
if(24-h>=10)
if(60-m>=10)

```
if(60<=t<480)
```
这一条语句有语法错误，应该是
```
if(60<=t&&t<480)
```
