Can't get it...

after the if statement, I dont know what code to put, to express that the tongue is faster or equal to the time in code.

the return type is bool and what i cant get is what to code in the body of the if statement to get the boolean return value.. Thanks a lot in advance.
I just did as following;

Frog.cs 
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;
        public readonly int ReactionTime;

        public Frog(int tongueLength, int reactionTime)
        {
            TongueLength = tongueLength;
            ReactionTime = reactionTime;
        }

        public bool EatFly(int distanceToFly)
        {   
            return TongueLength >= distanceToFly;
        }

        public bool EatFly(int distanceToFly, int flyReactionTime)
        {   
              if (TongueLength >= distanceToFly)
              {
                  return ReactionTime <= flyReactionTime;
              }

        }


    }
}

Hi Jeongeui Ji, if you click on preview, you can view the error message.

Frog.cs(18,21): error CS0161: `Treehouse.CodeChallenges.Frog.EatFly(int, int)': not all code paths return a value Compilation failed: 1 error(s), 0 warnings

The problem is that in cases where the first condition evaluates to false, no value will be returned from the method. One way to solve this would be to simply return false at the end, but it is possible to solve this challenge with just one line of code by combining both statements with the and operator (&&).

        public bool EatFly(int distanceToFly, int flyReactionTime)
        {   
              if (TongueLength >= distanceToFly)
              {
                  return ReactionTime <= flyReactionTime;
              }
              return false;
        }
