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
Answer:
10
Step-by-step explanation:
1/2 * 20 / 1 =
(20 * 1) / ( 2 * 1) = 10
You subtract 4 from 19=15, then sunbratce 6y from 3y= -3y. divide 15 by -3= -5. y= -5
