CheckSpeed

Hi guys, got stuck on this, could anyone help? Many thanks

Program.cs 
using System;

class Program
{

    static string CheckSpeed(double speed)
    {
        // YOUR CODE HERE
        double speed;
        if (speed > 65)
        {
            Console.WriteLine("too fast");
        }
        else if (speed < 45)
        {
            Console.WriteLine("too slow");
        }
        else
        {
            return Console.WriteLine("speed ok");
        }

    }

    static void Main(string[] args)
    {
        // This should print "too slow".
        Console.WriteLine(CheckSpeed(44));
        // This should print "too fast".
        Console.WriteLine(CheckSpeed(88));
        // This should print "speed OK".
        Console.WriteLine(CheckSpeed(55));
    }

}

  1. You don't need to declare speed variable. It will complain that is in local scope. You are already declaring it CheckSpeed(double speed).

  2. Console.WriteLine("too fast");

    It's asking you to "return" JUST the string as in return "too slow"

  3. "speed OK" instead of "speed ok". This shouldn't really matter here but code editor checks for it.
