Confused on why this isn't working, what am I missing?

I'm confused on what I need to return because the console keeps saying that it can't convert double to string

Program.cs 
using System;

class Program
{

    static string CheckSpeed(double speed)
    {

        if (speed > 65)
        {
           Console.WriteLine("too fast");
        } else if (speed < 45)
        {
           Console.WriteLine("too slow");
        } else
        {
           Console.WriteLine("speed OK"); 
        }

        return speed;
    }

    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));
    }

}

You need to set a return value at each statement as they are string values. Hope this helps.

return "to fast"; return "to slow"; return "speed OK;

Maybe it's because you're writing a line as a double
