```

@[BOATCHUANGU](/user/1466876) 两处printf都改了吗

@[laialaodi](/user/713554)
对的，都改了
```C
#include<stdio.h>
int main()
{
int s, v;
scanf("%d %d", &s, &v);
int t;
t = (s + v - 1) / v + 10;
int h, m;//h:m
m =60- t % 60;//求模取末尾
if
(t<=1440)
{
if (m != 60)
{
h = 7 - t / 60;
printf("%02d:%02d", h, m);
}
else
{
h = 8 - t / 60;
printf("%02d:00", h);
}
}
return 0;
}
```
