What is the average (mean) distance you walked?
Mon1 2/3 mi.
Tues 2 3/4 mi
Wed  3 1/3 mi.
Thurs.  1 2/3 mi.
Fri  2 3/4 mi.
You plan to walk on Saturday. How far must you walk on this day so that your 6 day average is 2 1/2 miles?

average = sum/5
average = (previous sum + x)/6
2.5 = (previous sum + x)/6
15 = previous sum + x
x = 15  previous sum 
sum = 1 8/12 + 2 9/12 + 3 4/12 + 1 8/12 + 2 9/12
sum = 9 + 38/12 = 9 + 3 2/12 = 12 1/6
av = (12 1/6) / 5
av = 2 2/30 = 2 13/30
part 2
x = 15  12 1/6
x = 14 6/6  12 1/6
x = 2 5/6
