This is a question similar to what will be on my test tomorrow. I'd really appreciate the help on how to figure this out.

The answer is 330 Pi or 1,036.7 miles.

the two towns form a sector with an angle

of 15º (53.6-38.6 = 15)

15º = pi/12 radians

you want the arclength of that sector

arclength = radius x angle

= 3960(pi/12) = 330pi
