Please just tell me, is the solution one of those Hashes which miner keeps to find and count? Or the solution is when a gazzillion of those hashes are calculated?
Depends on Hashrate AND Luck.
If you are extremely lucky, you find a block after 2 seconds with little hashrate.
If you are unlucky, you find a block after 8 months with big hashrate.
The more hashrate, the better.
