If each of the segments marked on the board above is of equal length, and if x and y represents the indicated lines on the board, then what is the distance between x and y? (There are 12 inches in a foot).
1) The board is five feet long.
2)x is 18 inches from the nearest end of the board.
There are 4 segments between x and y.
Thus, to determine the distance between x and y, we need to know the length of each segment.
Statement 1:
Length per segment = (total length of the board)/(total number of segments in the whole board) = (5 feet)/(10 segments) = 5/10 = 1/2 foot per segment.
Thus, the length of each segment = 1/2 foot.
SUFFICIENT.
Statement 2:
Length per segment = (total length between the left edge and x)/(number of segments between the left edge and x) = (18 inches)/(3 segments) = 18/3 = 6 inches per segment = 1/2 foot per segment.
Thus, the length of each segment = 1/2 foot.
SUFFICIENT.
The correct answer is
D.
