Let's say you have 1,000 minutes in your account. Minutes are normally earned by watching other members' websites through the automatic Traffic Exchange system. Read more about it here.
The minutes are used to deliver visitors to your websites. When submitting your website into HitsLikes.com, you can choose how long you want the visitors to stay on the website: between 10 and 60 seconds.
Let's also assume that you have submitted one website under My Websites, and the visit duration has been set to 30 seconds, which is 0.5 minutes. This is the amount of minutes that every hit will cost you.
Therefore, 1,000 minutes on your account will give you: 1,000 minutes / 0.5 minutes = 2,000 hits in total. If the visit duration is set to 60 seconds, you would receive: 1,000 minutes / 1 minute = 1,000 hits in total.
