A year on Mars lasts 687 days. Robot Pete lives on Mars. He is exactly 4 Mars years old.

That means he was born 2,748 days ago, assuming a robot was born, which makes no sense. But who cares! Robot Pete's older brother Jack was born 477 days before Pete. How many days old is Jack? Don't forget, to be older, Pete should be MORE days old than Jack! If your answer is less than 2,748 then think again.

1 answer

Jack is 3,225 days old.

To find Jack's age, we first calculate how old Pete is: 4 Mars years x 687 days = 2,748 days. Since Jack is older than Pete, we need to add the 477 days he was born before Pete to Pete's age: 2,748 days + 477 days = 3,225 days.

Therefore, Jack is 3,225 days old.
