Given numbers = 1, 5, 7, 9, 11

Add 13

New series = 1, 5, 7, 9, 11, 13

Total numbers = 6, which is even

For even numbers, median = average of middle 2 numbers

Middle 2 numbers = 3rd and 4th number = 7 and 9

Median = (7 + 9) / 2

= 16 / 2

= 8

So the order is:  

Green

Red ← between green and white  

White

Blue ← below green

The blue box is at the bottom.

Explanation

Step 1: Go 40 km North

Step 2: Turn left and go 40 km West  

Step 3: Turn right and go 30 km North

Now make coordinates:

Starting point = (0, 0)

After step 1 = (0, 40)

After step 2 = (-40, 40) 

After step 3 = (-40, 70)

Distance from start to end = sqrt[ (x)^2 + (y)^2 ]

= sqrt[ (-40)^2 + (70)^2 ]

= sqrt[ 1600 + 4900 ]

= sqrt[ 6500 ]

= 80.62 km

Approx distance = 80.6 km
