Световен рекорд по плуване

Някой може ли да ми каже къде са ми грешките (системата ми дава 60 от 100)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Globalization;

namespace TEST
{
class Program
{
static void Main(string[] args)
{

double record = double.Parse(Console.ReadLine());
double distanceInMeters = double.Parse(Console.ReadLine());
double timeInSeconds = double.Parse(Console.ReadLine());

double delayInSeconds = Math.Floor( distanceInMeters / 15) * 12.5;
double swimmingSeconds = (distanceInMeters * timeInSeconds) + delayInSeconds;
string newStr = string.Format("{0:0.00}", Math.Abs(record - swimmingSeconds));

if (swimmingSeconds >= record)
{

Console.WriteLine("No, he failed! He was {0} seconds slower.", newStr);
}

else
{
Console.WriteLine( "Yes, he succeeded! The new world record is {0} seconds.", Math.Round( swimmingSeconds , 2));
}
}
}
}

Кодът ми е за C++, акона някой му е от полза

#include <iostream>
#include <cMath>

using namespace std;
int main()

   {
       double record ;
       double metri ;
       double vreme ;
       cin>> record >> metri >> vreme;
       double razstoqnie = metri * vreme;
       double dobavka = floor(metri / 15)*12.5;
       double totaltime = razstoqnie + dobavka;
       if (record <= totaltime)
       {
           double nedostig = totaltime - record;
           cout.setf(ios::fixed);
           cout.precision (2);
           cout << "No, he failed! He was "<<totaltime-record<< " seconds slower." << endl;
       }
       else
       {
               cout.setf(ios::fixed);
           cout.precision (2);
           cout << "Yes, he succeeded! The new world record is "<<totaltime<<" seconds." << endl;
       }
   return 0;
   }
