解题思路:

注意事项:
ceil向上取整 最后结果取整
参考代码:

#include<stdio.h>

#include<math.h>

int main(){

    int num;

    double time=0.0;

    scanf("%d",&num);

    for (int i = 0; i < num; i++)

    {

        double x,y;

        int r;

        scanf("%lf %lf %d",&x,&y,&r);

        double long1 = sqrt((x*x)+(y*y));

        double time1 = (2*long1)/50;

        double time2 = r*1+r*0.5;

        double time3 = time1+time2;

        //ceil向上取整

        time = time+time3;

    }

    printf("%d",(int)ceil(time));

}
