Question

Total 380 invoices, approximately 1 minute and 38 seconds to process each. How long will it take me to complete?

Answer 1

4 hours and 28 minutes

Explanation:

1 minute and 38 seconds = 98 seconds

380 / 98 = 3.877551

3.877551

Seven rounds to 8 so the new number would be 3.88 which time wise would be 3 hours and 28 minutes.
