Jackson walks 2/3 miles to school ever day.how many miles does he walk after 12 days of school?

step 1
Find the average growth per year of the populations of rabbits farm A
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2 
numbers of rabbits=40 
average=[40-5]/2> 17.5

step 2
Find the average growth per year of the populations of rabbits farm B
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2 
numbers of rabbits=30
average=[30-5]/2> 12.5

step 3
Compare the average growth per year of the populations of rabbits on both farms

farm A=17.5
farm B=12.5
the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.

therefore

the answer is the option C)
the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.
