Let the principal be 'x' then the Amount will be 4x.
As the interest is compounded monthly:
Rate of interest = 10.1 % = 10.1/(100*12) = 0.101/12
Time = 12t
Amount = Principal[1 + Rate/100]
⇒ 4x = x[1 + 0.101/12]¹²t
⇒ 4x/x [1 + 0.008416667]¹²t
⇒ 4 = [1.008416667]¹²t
⇒ log(4) = log[1.008416667]¹²t
⇒ 0.602059991327 = [0.003640014891]¹²t
⇒ 12t = 0.602059991327/0.003640014891
⇒ 12t = 165.400419876
⇒ t = 165.400419876/12
t = 13.78 years or 13 years 9 months.
So, it is about 13 years 9 months she will have 4 times the amount of money.

Answer:
26.1miles
Step-by-step explanation:
If three cities A, B and C form a right triangle on a map, and the Cities B and C are the furthest apart, then the distance between cities B and C will be the hypotenuse of the triangle.
If cities A and B are 14 miles apart, then |AB| = 14miles
Also if cities A and C are 22 miles apart, then |AC| = 22miles.
To get |BC| which is the distance between cities B and C, we will use the Pythagoras theorem.
|BC|² = |AB|² + |AC|²
|BC|² = 14²+22²
|BC|² = 196+484
|BC|² = 680
|BC| = √680
|BC| = 26.1miles
This means that cities B and C are 26.1miles apart
1 thousand a month would be my guess
