Answer 2

7.31 times.

Explanation:

We have been given that Grand Canyon is approximately 29 kilometers long. Mariner Valley is a canyon on Mars that is approximately 212 kilometers long.

To find the number of times Mariner Valley is longer than the Grand Canyon, we will divide 212 by 29.

`(212)/(29)=7.3103448\approx 7.31`

Therefore, the Mariner Valley is 7.31 times longer than the Grand Canyon.
