Sam is 5 years old. His older brother, Tom, is three times as old as Sam. When Sam is 20, how old will Tom be?

NOW:

Sam -- 5 yrs
Tom--- 15 yrs

Tom will ALWAYS be 10 years older than Sam

take it from there

To determine how old Tom will be when Sam is 20, we need to find the age difference between them and add it to Sam's age when he turns 20.

Given that Sam is currently 5 years old and Tom is three times as old, we can calculate Tom's age as follows:

Tom's age = 3 * Sam's age
= 3 * 5
= 15

Now, let's find the age difference between them:

Age difference = Tom's age - Sam's age
= 15 - 5
= 10

To determine Tom's age when Sam is 20, we add the age difference to Sam's age at that time:

Tom's age when Sam is 20 = Sam's age when he is 20 + Age difference
= 20 + 10
= 30

Therefore, Tom will be 30 years old when Sam is 20.

To find out how old Tom will be when Sam is 20, we first need to determine the age difference between Sam and Tom.

Since Sam is currently 5 years old, we can calculate Tom's age by multiplying Sam's age by 3. Therefore, Tom is currently 5 x 3 = 15 years old.

To find the age gap between Sam and Tom, we subtract Sam's age from Tom's age: 15 - 5 = 10 years.

Now that we know there is a 10-year age difference between Sam and Tom, we can determine how old Tom will be when Sam is 20.

First, we find the time it takes for Sam to reach 20 years old by subtracting his current age from 20: 20 - 5 = 15 years.

Finally, we add the time it takes for Sam to reach 20 years to Tom's current age: 15 + 15 = 30.

Therefore, when Sam reaches 20 years old, Tom will be 30 years old.
