Difference in scanning time |
2007-02-08 |
|
From Lisa:
Boat 1 with 12,000 items on board with 7 days docking time limit Boat 2 with 12,000 items on board with 1 day docking time limit
Each item has to be scanned. We want to find out the difference in scanning time (in minutes and seconds). We tried this formula but with 60 minutes in one hour, 60 seconds in one minute, we are not sure if this formula is accurate.
