📝 Explanation Summary:

We used basic multiplication and division based on the standard time conversions:
- Multiply to go from smaller to larger units (e.g., minutes → hours).
- Divide to go from larger to smaller units (e.g., hours → minutes).

For multi-step conversions (like days → minutes), we break it down into steps using intermediate units.
