6) 5 years = ___ seconds
This is a multi-step conversion.
Step 1: Years → Days
- 1 year ≈ 365 days (assuming non-leap year)
- 5 years = 5 × 365 = 1,825 days
Step 2: Days → Hours
- 1 day = 24 hours
- 1,825 × 24 = 43,800 hours
Step 3: Hours → Minutes
- 1 hour = 60 minutes
- 43,800 × 60 = 2,628,000 minutes
Step 4: Minutes → Seconds
- 1 minute = 60 seconds
- 2,628,000 × 60 =
157,680,000 seconds
✔ Answer: 157,680,000
> Note: This assumes no leap years. If leap years are included, it would be slightly more, but for standard problems, we use 365 days/year.
