If you receive twenty dollars every 15 minutes, you can calculate your earnings for a six-hour shift as follows:
-
Convert six hours into minutes:
6 hours × 60 minutes/hour = 360 minutes. -
Determine how many 15-minute intervals are in 360 minutes:
360 minutes ÷ 15 minutes/interval = 24 intervals. -
Calculate your total earnings for those intervals:
24 intervals × $20/interval = $480.
So, you would make $480 after a full six-hour shift.
