How soon might I expect to generate a block? - https://en.bitcoin.it/wiki/Difficulty#How_soon_might_I_expect_to_generate_a_block.3F

time = difficulty * 2**32 / hashrate

$ python -c "print 20000 * 2**32 / 10**9 / 60 / 60.0" 23.85
 * For example, using Python we calculate the average time to generate a block using a 1Ghash/s mining rig when the difficulty is 20000:

510929738 * Math.pow(2,32) / Math.pow(10,9) / 60 / 60 / 24 / 365
 * So with the current difficulty 510,929,738, and a 1Ghash/s mining rig (faster than your CPU) you'd do this math:
