How to Calculate Age Difference between Julie and Michael

What is the age difference between Julie and Michael?

Julie is 14 years old. Michael is 2.5 times older than Julie. How old is Julie when Michael is 60?

Age Difference Calculation

To determine the age difference between Julie and Michael, we first need to find Michael's current age. Given that Michael is 2.5 times older than Julie, we can calculate: Michael's age = 2.5 * Julie's age = 2.5 * 14 = 35. Now that we know Michael's current age, let's calculate how many years it will take for him to reach 60 years old: Years until Michael is 60 = 60 - 35 = 25. Adding 25 years to Julie's current age won't give us the correct answer, as Julie will also be getting older during those 25 years. Therefore, we need to adjust the years until Michael is 60 by subtracting the current age difference between Michael and Julie: Adjusted years until Michael is 60 = Years until Michael is 60 - Age difference between Michael and Julie = 25 - (35 - 14) = 4. Adding this adjusted number of years to Julie's current age gives us the correct answer: Julie's age when Michael is 60 = Julie's current age + Adjusted years until Michael is 60 = 14 + 4 = 18 years. Therefore, when Michael is 60 years old, Julie will be 18 years old.
