Hi All answers round to 28 days or so. From the net: "The Moon makes a complete orbit around the Earth every 27.3 days (the orbital period), and the periodic variations in the geometry of the Earth–Moon–Sun system are responsible for the lunar phases that repeat every 29.5 days (the synodic period)."

So 29.5 days.
 
a) two new moons
b) two first-quarter moons
c) two full moons
d) two third-quarter moons

Thanks in advanced, all answers are appreciated.
