35
Well the way I look at it is... find the total distance between the two numbers and divide by 2. so... -15 is 15 away from 0, and 20 is 20 away from 0. I then add 15 and 20 together to get 35. I take 35 and divide by 2 to get 17.5. From here you can either add 17.5 to -15 or subtract 17.5 from 20. The answer is 2.5 Another way to look at this is with a line so... each period is equal to 1 number, the 0 in the line is the number 0 -15..............0...................20 You can see that the distance is greater on the right side because 20 is farther away from 0 than -15 is. You have to find the total distance between the -15 and 20 and divide by 0.

55 is the middle number on a number line from 20 to 90.
This is an approximate direct (straight line) distance. During actual travel, this distance may change if a different flight route is chosen. The distance between the two places in miles is: 20
31
To the left of 0, between -21 on its left and -19 on its right.
