Ответ:
(40+F) * time = 210 miles
( 40 - F) * 2 * time = 380, takes it twice as long to go 380 as 210 down stream
F is the flow and time it time.
solve the first for time = 210/(40+F) sub into the second
use the quadratic on line solver
flow = 39.9
my equations turned out to be -21F^2 -19F + 32840 = 0
one real root and one negative root, discard the negative root.
