Answer: 7 years old
Explanation: so first we know he has to be at least 1 year old. we can think of the multiples of 9 that are greater than 56 because he will be 9 times as old. so 63 is a multiple of 9. 63-56=7. kevin is 7 right now, and in 56 years, he’ll be 63, which is 9 times as old as he is now.
hope this helped!
