Step-by-step explanation:
LORAN follows an hyperbolic path.
The equation of the hyperbola is: 
The coordinates are given as:

The center of the hyperbola is

The distance from the center to the focal points is given as:

Square both sides

The distance from the receiver to the transmitters is given as:

Divide both sides by 2

Square both sides

We have:

This gives

The equation of an hyperbola is:

So, we have:


Hence, the equation of the hyperbola is:

Answer:
b = 5
Step-by-step explanation:
28.95 + 34b ≤ 200
34.05b ≤ 200 - 28.95
34.05b ≤ 171.05
b ≤ 5.023
b = 5 is the answer
check: 5 * 34.05 + 28.95 = 199.2
if b=6: 6 * 34.05 + 28.95 = 233.25
