Final answer:
To find the total length of the zipline Kevin combined, multiply the number of sections (11.5) by the length of each section (3 feet), resulting in a total of 34.5 feet, or answer choice (a).
Step-by-step explanation:
The question asks us to calculate the total length of zipline Kevin combined. Given that each section of the zipline is 3 feet long and there are 11 and a half sections, we can calculate the total length by multiplying the number of sections by the length of each section.
- Find the total number of sections: 11.5 sections
- Multiply the total number of sections by the length of each section (3 feet): 11.5 sections × 3 feet/section = 34.5 feet
Therefore, the total length of the zipline that Kevin combined is 34.5 feet, which corresponds to answer choice (a).
