I really can't figure out where im going wrong on this code..

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 
        {
       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));
    }

}

Your code is very close, but the question is asking you to return a string with the method, not to write to the console. All of the paths in the "if" statement should have a return ("string text goes here");

You can’t return Console.WriteLine(in else you do that). You either Console.WriteLine or you return something(like a bool,int, String, Object). Based on your method signiture, you want to return a String.

static String checkSpeed(double speed)

In each if/else statement return a string.
