It results in the correlation of the environments between the biological relatives raised in two different homes.
<u>For example, when the child is placed in a home which is similar to the home of the biological parents.</u>
V = d/t = 10m / 5 s = 2m/s
point a to point b = 2m/s
point b to point a = 2m/s
avg speed = (2m/s+2m/s)/2 = 2m/s
avg velocity= (2m/s+2m/s)/2 = 2m/s
