Answer:
10.6
Step-by-step explanation:
Substitute 136.5 for y.
Compare this equation with 
a = 1, b = - 191, c = 8190
or
or
or
or
or
or
x = 126 or x = 65
Hence, the points on the curve are (65, 136.5) and (126, 136.5).
The width of the air space is the distance between these points.
Width = 
= 
= 126 - 65
= 61
Hence, width of the air space is 61m.
Okay Abrahammontiel1, the thing you must remember is any thing that is 5 or over must be rounded up and anything lower must be rounded down.
Example:
$2.30
since we want to round to the nearest dollar we look at the digit behind the whole dollar, which in this case is 0.3
and since it's lower that 0.5 we must round down
So it will look like this: $2
If we had a number like $4.72
we would look at the 0.7
and since it is greater that 0.5 we would round up so that it would equal $5
