To determine the average, you need to add up all the numbers within the table and then divide by how many numbers there are. 14 + 23 + 13 + 13= 37 + 26 = 63. We have a sum of 63 and a total of 4 numbers. Divide the sum by the total amount of numbers. 63/4 = 15.75 The average is 15.75 km, which is more than 15.00 km. I hope this helped!
