Question Completion Status 6.21 10 p QUESTION 2 Sometimes we must use multiple conversion factors to get where we want. Example: How many seconds are there in 5.5 day? Normally, we don't know the direct conversion factor, but we all should know the following 1 day 24 hours (h) 1 hour 60 minutes (min) 1 minute 60 seconds (s) To convert from days to seconds, we just string out the conversion factors n factors 5.5 days x 1 day 24h...
