Let wind speed = x mph
when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x = 2 / t -------(1) where t is the time she took.
when riding with the wind we have
20 + x = 3 / t--------(2) adding equations (1) and (2):-
40 = 2/t + 3/t
40 = 5/t
t = 5/40 = 1/8 hr
x = 20 - 2 / 1/8 = 20 - 16 = 4
Wind speed was 4 mph Answer

Answer:
1545.62
Step-by-step explanation:
The calculation of compound interests uses this formula:
<h2>

</h2>
Where A = total amount, P = principal or amount of money deposited, r = annual interest rate, n = number of times compounded per year and t = time in years.
So, if we plug-in the numbers of the problem we have:
<h2>

</h2>
Which gives us:

For a grand total of 1,545.62 including capital and interests.
