If you calculate the speed near the equator, you have to divide the circumference of earth at the equator by the time it makes one revolution: That is 24,900 miles divided by 24 hours which sums up to equal almost 1037 miles an hour.
Currently, Nutrisystem through Costco has $100 e-gift cards for $54.99. I tried to order 10 (the maximum) e-gift cards (for a total of $549.90) through Costco, but about 20 minutes later I recâd an e-mail stating that the order was canceled.
To figure out your own Nutrisystem cost, you should figure out how long you'll need to be on Nutrisystem to reach your goal weight. Then calculate the total cost of the plan. For example, if you need to lose 30 pounds and you lose 1-2 pounds per week, you'll need to be on Nutrisystem for about 15 weeks or 3-4 months.
