The range equation tells you:
R = v0^2 sin(2 theta)/g
before plugging in any numbers, notice that the only difference between the earth and moon is the accel due to gravity. Since range and gravity are inversely related (when one increases, the other decreases), you should be able to see that since g on the moon is 1/6 the value of g on the earth, the range on the moon must be times times greater than the range on the earth. If the distance on earth is about 17 meters, the range on the moon is six times that amount. Similarly, since time of flight is given by
t = 2 v0 sin theta/g
the time on the moon is six times the time of flight on the earth.
