<h2>Answer:</h2>

The distance that a tortoise will cover in 6 hours is:

                        16.47735 feet.

<h2>Step-by-step explanation:</h2>

It is given that :

A tortoise travels 11 feet in one hour.

In each subsequent hour, the tortoise travels one-third the distance it traveled in the previous hour.

  • This means that in 2 hours it travels a total of:

11+\dfrac{1}{3}\times 11\ feet

which is equal to:

11\times \dfrac{4}{3}\ feet=\dfrac{44}{3}\ feet

  • in the 3 hours it will travel a total of:

=11+\dfrac{1}{3}\times 11+\dfrac{1}{3^2}\times 11\ feet

  • In 4 hours it will travel a total of:

=11+\dfrac{1}{3}\times 11+\dfrac{1}{3^2}\times 11+\dfrac{1}{3^3}\times 11\ feet

  • In 5 hours it will travel a total of:

=11+\dfrac{1}{3}\times 11+\dfrac{1}{3^2}\times 11+\dfrac{1}{3^3}\times 11+\dfrac{1}{3^4}\times 11\ feet

  • In 6 hours it will travel a total of:

=11+\dfrac{1}{3}\times 11+\dfrac{1}{3^2}\times 11+\dfrac{1}{3^3}\times 11+\dfrac{1}{3^4}\times 11+\dfrac{1}{3^5}\times 11\ feet=16.47735\ feet

                     Hence, the answer is:

                               16.47735 feet
