every contest is 15 minutes, and i win every 15 minutes 600 dollars, i need 28,000 dollars, and i have 3 hours to get 28,000 dollars. I have 9,705 dollars, will i have enough time to reach 28,000 dollars?

To calculate whether you will have enough time to reach 28,000 dollars, we need to determine how much you can earn in 3 hours and add it to your existing balance.

Since each contest lasts 15 minutes and you win 600 dollars every 15 minutes, we can calculate your earning rate as follows:
600 dollars / 15 minutes = 40 dollars per minute

Now, we can calculate how much you can earn in 3 hours by multiplying your earning rate by the total number of minutes in 3 hours:
40 dollars/minute * 180 minutes = 7,200 dollars

Therefore, you can earn an additional 7,200 dollars in 3 hours. Adding this amount to your current balance:
9,705 dollars + 7,200 dollars = 16,905 dollars

As a result, even after 3 hours, your total balance will only be 16,905 dollars, which is still far from reaching 28,000 dollars. So, you will not have enough time to reach your goal within the given timeframe.
