Final answer:
Thomas is 50 years old currently. This was determined by setting up equations expressing the given age relationships and solving for the unknowns.
Step-by-step explanation:
The subject of the question is a mathematical problem involving age and ratios. We are given that Thomas is currently 5 times older than Daphne and that in 10 years, he will be 3 times older than Daphne. To solve this problem, we can set up two equations based on this information:
Let's denote Thomas's age as T and Daphne's age as D.
Currently: T = 5D
In 10 years: T + 10 = 3(D + 10)
We can now substitute the first equation into the second:
5D + 10 = 3(D + 10)
5D + 10 = 3D + 30
Now, solve for D:
2D = 20
D = 10
Now that we have Daphne's current age, we can calculate Thomas's current age:
T = 5D
T = 5 × 10
T = 50
So, Thomas is currently 50 years old.
