We effectively rewrite the equation as
In order for the LHS to be defined, we need to restrict , or
. Now, the LHS will vanish when the numerator is 0, which happens for
This value is indeed smaller than 4, so the solution is .
We first approach this problem by forming a diagram. Refer to the attachment.
You might notice a right triangle forming when you connect cities A, B, and C. In this case, we'll just need the Pythagorean theorem when solving for the distance between city B and city A.
ANSWER: The distance between city B and city A is 85.96 kilometers.
