what is wrong

the error: "If the frog's reaction time and tongue length are the same as the fly's reaction time and its distance, the frog will eat the fly." whats wrong?

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 )
        {
            return TongueLength+ReactionTime >= distanceToFly+flyReactionTime && ReactionTime >flyReactionTime;
        }

    }
}

The instructions for this step of the challenge:

Add another method named EatFly that takes two integer parameters and returns a boolean value. Name the parameters distanceToFly and flyReactionTime. Return true if the frog’s tongue is longer or equal to than the distance to the fly and its reaction time is faster or equal to than the fly’s reaction time.

Ignoring the extra thans, which are just bad english, you can use the second sentence as a model for your function:

  1. frog’s tongue is longer or equal to the distance to the fly = TongueLength >= distanceToFly
  2. and = &&
  3. reaction time is faster or equal to the fly’s reaction time = ReactionTime <= flyReactionTime

Part 1 is already done in the other EatFly method, so the final method will look like:

public bool EatFly(int distanceToFly,int flyReactionTime )
{
    return EatFly(distanceToFly) && ReactionTime <= flyReactionTime;
   // or 
   // return TongueLength >= distanceToFly && ReactionTime <= flyReactionTime;
   // if you don't want to call the other EatFly method
}
