The correct answer is:
$1560\text{ hours}$
Explanation
Convert days to hours using the fact that there are 24 hours in one day, then multiply.
Steps:
- Conversion factor: $$1\text{ day} = 24\text{ hours}$$
- Multiply: $$65 \times 24 = 1560$$
- Include units: $$1560\text{ hours}$$
Therefore, 65 days equals $1560\text{ hours}$.
