Age Relationships and Equations

The video tutorial covers two age-related word problems. The first problem involves calculating how many years it will take for Salman to be four times as old as Jonathan. The solution is reached through algebraic equations, determining that it will take four years. The second problem involves Tarush and Arman, where Tarush is five times as old as Arman today and was ten times as old 85 years ago. The solution process is shown, but the final answer is not confirmed due to time constraints.

What is the initial age difference between Salman and Jonathan?

• 82 years

• 86 years

• 88 years

• 84 years

If y represents the number of years until Salman is four times as old as Jonathan, what equation represents this scenario?

• 108 + y = 4(24 + y)

• 108 + y = 3(24 + y)

• 108 + y = 5(24 + y)

• 108 + y = 2(24 + y)

What is the relationship between Tarush and Arman's ages today?

• Tarush is 3 times as old as Arman

• Tarush is 4 times as old as Arman

• Tarush is 5 times as old as Arman

• Tarush is 6 times as old as Arman

How old was Tarush compared to Arman 85 years ago?

• Tarush was 8 times as old as Arman

• Tarush was 9 times as old as Arman

• Tarush was 10 times as old as Arman

• Tarush was 11 times as old as Arman

What is the equation used to solve for Arman's age today?

• 5x - 85 = 7(x - 85)

• 5x - 85 = 10(x - 85)

• 5x - 85 = 9(x - 85)

• 5x - 85 = 8(x - 85)
