25 pointsplease help very hard

Answer 1

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!
