This has to do with the distance that the earth has moved around the sun in that time. The earths progression in that time means that the moon has to travel a little further to get back to the same position relative to earth and the sun (synodic period). This synodic period is longer than the sidereal period, which is the true orbit time of the moon relative to the stars.

Your question is not complete; slowed doen by how much? right now it takes 29.5 earth days for the moon to make one complete revolution around Earth. So if the speed of moon slows down by half of what it is now, then it would take twice as much time as it take now revolve around Earth
