Answer 2

Calculating Age Difference:

To find out how many years it will take for Angelina to be twice as old as Marina, we can use the following equation:

Let x = the number of years it will take for Angelina to be twice as old as Marina.

So, Angelina's age after x years will be 15 + x, and Marina's age after x years will be 5 + x. According to the given condition, Angelina's age after x years will be twice Marina's age after x years.

Therefore, the equation becomes: 15 + x = 2 * (5 + x)

Let's solve for x:

15 + x = 10 + 2x x = 5

So, it will take 5 years for Angelina to be twice as old as Marina.
