#include <stdio.h>
int main()
{
    int s,v;
    scanf("%d %d",&s,&v);
    int min = (double)s/v+10;
    int a = 8 * 60 - min;
    printf("%2d:%2d",a/60,a%60);
    return 0;

printf占位符是%02d吧

@Steve_xh 还有其他错的地方

前面没补 0 而且算错了

@great_mad

1. 时间向上取整 min = ceil(s*1.0/v)+10
2. 有可能要在前一天就出发 if(a<0) a+=1440;
