Let's solve the problem ... Take, Width of river = d. Speed of A initially = A Speed of B initially = B time for the first trip = t1 time for the second trip = t2 First trip:- for A, d = A×t1 ---> (1) for B, (d-400) = B×t1 ---> (2) sub (1) in (2), we get, (A×t1)-400 = (B×t1) (A-B)t1 = 400 ---> (3) Second trip, for A, d = 2A×t2 ---> (4) for B, d/2 = 2B×t2 ---> (5) sub (4) in (5), we get, A×t2 = 2B×t2 A = 2B ---> (6) sub (6) in (3), we get, (2B-B)×t1 = 400 B×t1 = 400 ---> (7) sub (7) in (2), we get, d - 400 = 400 d = 800 therefore, the width of the river d= 800. Hence, Solved.
"When they started swimming, A was ahead of B by 400 meters... Therefore, the final result is that the width of the river is 2400 meters."

what about Rune Masters? What about his rune mastery? Don't you think we are going off-track here? Don't forget that this story about spells. Even the name of the story tells that. So get back to track ASAP.
I have this story. I hate how it makes me wants to read it without stopping. I hate how's it makes me addicted with just a few chapters.
umm, not children but cooldown

50% reduced children in any one of his skills that he selects. This will be applicable as long as he does not change the affix in between.
I accept with the above comment. This one is a gem in the rough. It is incorporating both fantasy and science fiction together. The plot is taking shape well. There are these obvious cliches taking place and it seems some different scenarios will take place too. We could at least support him a little by commenting on his story.
Bro, your logic is wrong. the two trips are seperate. So, you shouldn't take the remaining distance into account. That way of solving won't work. This is a substitution problem, with the relation of speed, distance and time. the equation should be distance = speed × time. with this we could eventually solve it after a few substitutions.
