Hi, 
Im not very sure about what a fairway and hang time are, i think hang time is the time of flight. 

The vertical component of vel will be 0 at max ht. Thus 
Uy^2 = 2*gH where uy is the vertical component of initial vel. Thus H = 20 m. Also the horizontal motion is uniform. 
Ux*t = R where R is max horizontal distance. 
Now, using Uy = gt as Vy = 0, t for reaching max ht time is found. Twice this time will be taken to fall on ground. Thus,
74*4 = R = 296. 

Please tell me what a fairway is! ;-)

@Justanotherguy Just a road probably. it doesnt even matter to the problem. We are just starting with parabolas in physics so no wind resistance or anything high level.
