#include<stdio.h>
int main(){
    double s,v;
    int m;
    scanf("%d%d",&s,&v);
    m=24*60-(s/v+10)+8*60;
    printf("%02d:%02d",(m/60)%24,m%60);
    return 0;
}

@kitkit

scanf 读入 double 不是 %d 而是 %lf 。

#include<stdio.h>
int main(){
    double s,v;
    int m;
    scanf("%lf%lf",&s,&v);
    m=24*60-(s/v+10)+8*60;
    printf("%02d:%02d",(m/60)%24,m%60);
    return 0;
}

新手菜坤建议用cin，cout @kitkit

@kitkit scanf("%d")是输入int类型，double是scanf("%lf")
