Two cyclists start from point $A$ towards point $B$. Cyclist 1 rides at a consistent speed which is increased by a constant wind speed aid, while Cyclist 2 rides at a consistent speed but against the constant wind, slowing her down. Both start at the same time; Cyclist 1 reaches point $B$ then immediately returns towards $A$, and meets Cyclist 2 halfway back from $B$ to $A$ 4 hours after both initially started. If the wind aids or resists them by altering their speeds by 3 km/h, what was the duration of the trip for Cyclist 1 from $A$ to $B$?
A) 1.5 hours
   B) 2 hours
   C) 2.5 hours
   D) 3 hours
   E) 3.5 hours
