Answer :
that would just be the total distance over the number of runs. so -15 3/4 divided by 9. -15 3/4 is equal to -63/4. -63/4 *1/9 = -7/4 or a loss of 1 3/4 yards per run.
Answer: 1.75 yards / time = 1 3/4 yards / time
Explanation:
Average changes involve calculations using only final and initial values, i.e. it does not matter what happens in between.
In this case, the average change in field position is the total loss of yards divided by the number of times that the ball was carried:
average change = total loss of yards / number of times the ball was carried
total loss of yards = 15 3/4 yards = 15.75 yards
number of times the ball was carried = 9 times
average change = 15.75 yards / 9 times = 1.75 yards / time
1.75 = 1 3/4
average change = 1 3/4 yards / time
