The average is 4 3/4 km.
you would have to add the distance she ran for each day and then divide by the number of days she ran to find the average.
5 1/2 + 6 1/4 + 4 1/2 + 2 3/4 =19
19 (the total distance ran) divided by 4 (the number of days) = 4 3/4
Divide 180 by 5 to get A-36
The square root of 63 is 7.93725393319
7.937253319 * 7.937253319 = 63
