10281 - Average Speed

[tzupengwang]

I get AC now~
But it's not a precision problem
it's a input problem with the first line
it's not necessary to have a "speed" input at the end of the first line
Thank you very for your help !!!
I really appreciate it

            speed=0;
            temp=len-1;
            i=1;
            while(temp>8)
            {
                speed+=(time[temp]-'0')*i;
                i=i*10;
                temp--;
            }
            first=second;
        }

    }
    return 0;
}

Try using double instead of float
