In order to solve for an average for this problem, you have to add all the numbers and divide by three. So, add 3.05 and 2.74 and you get 5.79. Then add 5.79 and 3.3, which equals 9.09. Now all you have to do is divide it by 3. Therefore, the answer is 3.03 meters. Good luck; cheers, mimiisawesome5
