Ben is 30 years old and Daniel is 2 years old.
How many years will it take until Ben is only 3 times as old as Daniel?
Answers
Answer:
Finally, it would be 12 more years (14 - 2 = 12) before Daniel will be 14.
The answer is 12 years.
Step-by-step explanation:
Let: D = Daniel's age
B = Ben's age
Given: Ben is 30 when Daniel is 2.
Ben is 28 years older than Daniel
30 - 2 = 28
Therefore, at anytime: B = D + 28
We want to know their ages when B = 3D:
B = 3D
B = D + 28
Therefore: 3D = D + 28
3D - D = 28 subtract D from both sides
2D = 28 combine like terms
D = 14 divide both sides by 2
Therefore, when Daniel is 14, Ben will be 14 + 28 = 42 which is 3X Daniel's age.
Finally, it would be 12 more years (14 - 2 = 12) before Daniel will be 14.
The answer is 12 years.
