I am having trouble with this problem. If anyone can help it will be greatly appreciated.

Speakers A and B are vibrating in phase. They are directly facing each other, are 8 m apart, and are each playing a 77 Hz tone. The speed of sound is 343 m/s. On the line between the speakers there are three points where constructive interference occurs. What are the distances of these three points from speaker A?

near, farther, and farthest.
