Question

The Greenland shark is thought to be the longest-living vertebrate on earth. Early estimates of its maximum age were based on the fact that such sharks grow in length only about a centimeter per year, and yet an adult shark can reach a length of 15 feet. Estimate how long an 11 foot shark might have lived.

Answer 1

An 11 foot (335 centimeter) might have lived 335 years

Step-by-step explanation:

The length of the 11 foot shark in centimeter = 11 foot × 100cm/3.2808 foot = 335cm (to the nearest whole number)

A shark grows 1 centimeter in length in 1 year

Therefore, the time taken for the shark to grow 11 foot (335cm) is 335 years

So, an 11 foot shark might have lived 335 years
