Disclaimer: I don't speak probability language.
Let restate the 1st row in term of real units rather than abstract terms. The 1st row says "in a set of experiments of the same conditions Exp1 with 100 batches of raw material it produces 87.89 batches of products in 3.86 hours."
Similarly, the second row says: "in a set of experiments of the same conditions Exp2 with 100 batches of raw material it produces 91.08 batches of products in 18.08 hours."
If we have few hours to do thing, 4 hours for example, we would choose the first method since we don't have time to do the second.
But if let say we have all the time in the universe, and let say we have 100 hours and enough raw material that we can do 100 batches of raw material at a time, which method do we choose?
1. 87.89*(100/3.86) = 2,276.94 batches
2. 91.08*(100/18.14) = 502.09 batches
So we would prefer method Exp1. Do I make any sense?
