Distance

by gmattester » Fri Aug 22, 2008 11:21 am
The figure above shows the number of meters in the lengths of the four sides of a jogging path. What is the total distance around the path? [See Attachement]
(1) One of the sides of the path is 120 meters long.
(2) One of the sides of the path is twice as long as each of the two shortest sides.

I guessed so.
B - stmt 2 is sufficient since 2x = x+60; 2x cannot be equal to 3x, the only side remaining is x+60

I think the answer should be B.

Statement I

120 can be any of the three sides. Therefore Insufficient.

Statement II

one side is twice the other two shorter sides.

3x = 2x
or
x+60 = 2x

3x cannot be equal to 2x for any positive integer. Therefore x+60 =2x

x=60

Sufficient.

Hence B.
