Answer = 25
Explanation
Area divided by width: 475 / 19 = 25
Therefore answer is: Width - 25m
Since OC is perpendicular to AB, the line AB gets split evenly. So

So AB=2*6.7=13.4
Ans: Option B, 13.4 units
The height of the track will be given by:
sin θ=opposite/ hypotenuse
θ=34°4'=34+4/60=34 1/15°
thus
sin 34 1/15=h/68.8
h=68.8sin 34 1/15
h=38.54 meters
