The endpoints of a line segment are at the coordinates (–6, 3, 4) and (4, –1, 2). What is the midpoint of the segment?

a
(–1, 1, 3)

b
(–2, 2, 6)

c
(–10, –2, 2)

d
(–5, –1, 1)

Step-by-step explanation:

Use the midpoint formula:

We want to find the midpoint of the line

that has endpoints.

We simplify to get;

This finally gives:

The correct answer is A.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
