In order to carry out this amazing feat of calculational legerdemain, you have to know that 1 minute = 60 seconds. Gather an audience and proceed as follows: If 1 minute = 60 seconds, then 30 minutes = (30) times (60 seconds) = 1,800 seconds. As the crowd goes wild, you gratefully acknowledge the cheers and applause, smile and take your well-deserved bow. Caution: They'll beg for an encore. You'll be tempted by their adulation, but don't do it ! Always leave them wanting more.
There are 60 seconds in a minute, so a half minute would be 30 seconds. If you have a length of time in half minutes, multiply that by 30 to get seconds. For example, 20 half minutes = 20 x 30 seconds = 600 seconds
4 minutes 30 seconds
30 minutes = 1,800 seconds
19 minutes 30 seconds minus 12 minutes 40 seconds = 6.833 minutes OR 6 minutes 50 seconds.
When you add 5 minutes and 40 seconds to 8 minutes and 50 seconds, the total is 14 minutes and 30 seconds.

30 minutes = 1,800 seconds
1 hour = 3600 seconds 30 minutes = 1800 seconds 1 hour + 30 minutes = 5400 seconds
19 minutes 30 seconds minus 12 minutes 40 seconds = 6.833 minutes OR 6 minutes 50 seconds.
