🛎️ What are Units of Time?
- Time is measured in seconds (s), minutes (min), hours (h), and days.
- The conversion rates you must know: 60 s = 1 min, 60 min = 1 h, and 24 h = 1 day.
🛎️ How to Convert Units of Time?
- Converting to a smaller unit means multiplying; converting to a larger unit means dividing.
- For example, 2 h = 120 min (×60) and 300 s = 5 min (÷60).
🛎️ How to Add Time?
- Add minutes and seconds separately.
- If seconds are 60 or more, convert 60 s into 1 min.
🛎️ How to Subtract Time?
- Subtract minutes and seconds separately.
- If there are not enough seconds, exchange 1 min for 60 s first.
