1) The road distance from exit J to exit L is 21km.

2) The road distance from exit K to exit M is 26km.

Why is E the correct answer and not C? I got KL as 5km (26-21 overlap) and hence answer C. Thanks!


If you use both (1) and (2), you see that even if JL and KM are given, there´s nothing conclusive about KL. JL and KM could overlap completely OR just partially. Thus E.

i chose E.

drawing a number line was helpful to me. if J is at zero and L is at 21, K could be anywhere from 1 to 20 with M being anywhere from 27 to 46. the distance from K to L would change depending on where K and M are on the number line.

Easiest way is to draw a picture

draw J K L & M

Then draw an arch from J to K, label it 21
then an arc from K to M

You want the distance from K to L, but L can be anywhere between K & M.... quick E
