Suppose that two asteroids in the asteroid belt are moving in a straight line and at the same speed toward each other. If a 3D coordinate system is placed with the origin at the sun, then the position of one asteroid can be described as 2.8 astronomical units (AU) in the direction of positive x, 0.3 AU in the direction of positive y, and 0.15 AU in the direction of positive z. At the same time, the position of the other asteroid can be described as 2.7 AU in the direction of positive x, 0.23 AU in the direction of positive y, and 0.12 AU in the direction of positive z. At what point in this 3D coordinate system will they collide? Use the midpoint formula
i have tried to solve this by using the formula but i cant figure out x2,y2 and z2.
