Leon already ran 1 miles on his own and he is expected to cover a distance d of 3 miles during each practice. The number of practices is expressed as p and the distance covered is expressed as d.
For every track practice he is expected to cover a distance of 3 miles. Recall he has already cover 1 mile on his own.
Therefore, the relationship between the practices p and the distance d can be expressed as follows.
number of track practice = p
distance covered = d
The distance covered d in miles is 1 miles plus the number of track practice p multiply by 3
So z-4 2/3=2 2/3 so 4 2/3=12/3+2/3=14/3 2 2/3=6/3+2/3=8/3 z-14/3=8/3 multiply both sides by 3 3z-14=8 add 14 to both sides 3z=22 divide both sides by 3 z=22/3=7 1/3
