Question

On a subway route, station C is located at the midpoint between stations A and D. Station B is located at the midpoint between stations A and C. If the distance between stations A and D is 2.4 kilometers, what is the distance between stations B and D?

Answer 1

So first, you have to find the midpoint of A and D, which is C. Then you have to find the midpoint between A and C.

A =0
D = 2.4
B = ?
C=?

C = 2.4/2 = 1.2km
B = 1.2/2 = 0.6km

Answer 2

2.4-0.6 = 1.8km

So the distance between B and D is 1.8 km

Answer 3

I would argue this question... but I tend to be that way...
