Step-by-step explanation:
I hope I understood this correctly.
So.. traveling without the wind, let's say the pedalist has a speed of "r"
with the wind, the wind's rate is added to it, so, he's not going "r" fast, he's really going r+3 fast
against the wind, he's going r - 3 fast
notice, he covers 30 miles with it, and 18 miles against BUT the time for both ways is the same, say time "t"
now, recall your d = rt, distance = rate * time
thus
solve for "r"
