Question

Nora's grandfather has a very old pet tortoise. He told Nora that the tortoise was 56 years old when she was born 11 years ago. Nora is amazed and wants to know how old the tortoise is now.

Answer 1

If the tortoise was 56 years old when Nora was born 11 years ago, we can calculate the tortoise's current age by adding those 11 years to its age at the time of Nora's birth.

Tortoise's age when Nora was born: 56 years
Years since Nora was born: 11 years

Current age of the tortoise = 56 years + 11 years = 67 years

So, the tortoise is now 67 years old.
