To find the number of years an initial capital will double, we use the following approximation:
Number of years needed to double a capital = 70/interest rate (without the %)
The rate being 5, Number of years = 70/5 = 14 years,
Proof: (Remember te formula of compound interest A = P(1+interset)ⁿ
1200 = 600(1+5%)ⁿ
1200/600 = (1.05)ⁿ
2= (1.05)ⁿ
ln(2) = (n)ln(1.05)
0.693147181 = (n)(0.048790164)
n= 0.693147181/0.048790164
n= 14.26 years ≈ 14 years
3679 your just gonna subtract 11,472 from the miles he still has left which is 7793 so your answer is 3679

To convert the distance that is given in yards to miles, we use the conversion factor,
1 yard = 0.000568 miles
which is also equal to
1 mile = 1760 yards
With these conversion factor we convert the given,
(2180 yards) x (1 mile / 1760 yard) = 1.24 miles
