True, False, True

Explanation:

Since the leaf falls #18# feet to get to the ground, its height should be #18# feet.

The leaf falls #5# feet per #2# seconds, or #5/2# feet per #2/2# (#1#) second, not #2/5# feet per #1# second.

To be #3# feet above the ground, the leaf must have fallen #15# feet. #15# is #3# times #5#, and it takes #2# seconds for the leaf to fall #5# feet, so it must have taken the leaf #2*3# seconds to fall #3*5# feet.

#2*3=6#
