c语言代码解决问题

解题思路:

注意事项:

参考代码:

#include<stdio.h>

#include<math.h>

int main()

{

    int n;

    double sum_time = 0.0;

    scanf("%d", &n);

    while (n--)

    {

        int m;

        double x, y,distance,length,time;

        scanf("%lf %lf %d", &x, &y,&m);

        length = x * x + y * y;

        distance = 2*sqrt(length);

        time = distance / 50+(double)m*1.5;

        sum_time += time;

    }

    printf("%.0lf", ceil(sum_time));

    return 0;

}
