Lines m and n are parallel and 12 inches apart. Two distinct lines p and q are parallel to m, and are each twice as far from m as from n. If all the four lines lie in the same plane, what is the distance, in inches, between p and q?

(A) 8

(B) 12

(C) 16

(D) 20

(E) 24

......................................................m

12 inches

.......................................................n

P Q also parallel

but their distance from m is twice the distance from n

Hence one of them will be in between m and n and one below n (If the line is above m then distance from m will be less than distance from n)

......................................................m

8 inches

.......................................................p

4 inches

.......................................................n

12 inches

.......................................................q

p is 8 inches from m and 4 inches from n

q is 24 inches from m and 12 inches from n

Between p and q 16 inches

C
