+------------------------------------------+
The distance (in miles)  is a function of an orange strip.
Orange strip 1 is 1/4 mile; orange strip 2 is 1/2 miles;
orange strip 3 is 3/4 miles; orange strip 4 is 1 mile; etc.

d(n) = (1/4)(n)  miles    ...or...  d(n) = (n)/4  miles

d    is the function name
n    is the orange strip number
d(n) is the number of miles at orange strip 'n'

d(0) = (1/4)(0) = 0 mi.
d(1) = (1/4)(1) = 1/4 mi.
d(2) = (1/4)(2) = 2/4 = 1/2 mi.
d(3) = (1/4)(3) = 3/4 mi.
d(4) = (1/4)(4) = 4/4 = 1 mi.

the numbers are:  1/4  1/2  3/4  1  (1 1/4)  (1 1/2)  (1 3/4)
2  (2 1/4)  (2 1/2)  (2 3/4)

the math is:  (1/2 * (1/4 + 3/4 + 1) + 2) * (1 1/4 + 1 3/4) -
(1 1/2 + 2 1/2) - 2 1/4 = 2 3/4

observe...
1/4 + 3/4 = 1  and  1 1/4 + 1 3/4 = 3
1 1/2 + 2 1/2 = 4  and  2 1/4 + 2 3/4 = 5
