To find the farthest distance the one long hose can reach, you need to add the lengths of all three hoses together:
- Brown hose: 10.75 feet
- Green hose: 16.4 feet
- Black hose: 8.5 feet
Now, add these lengths together:
\[ 10.75 + 16.4 + 8.5 = 35.65 \text{ feet} \]
So, the farthest distance the one hose can reach is 35.65 feet, which corresponds to option d. 35.65.
