This happens because the trucks move in one-dimension, while the airplanes move in 3 dimensions.

<h3></h3><h3>Why the trucks need to change direction or speed while the airplanes don't?</h3>

Well, the trucks move along a street. Thus, we can think that this is an one-dimensional kind of motion.

Where the trucks can go forward, backward, or get out of the line.

In the case of the airplanes, they can move actually in 3 dimensions (the airplane can go upwards, downwards, left, right, etc).

Now, in the one-dimensional case of the trucks there are only two directions (which are opposite) so if the trucks travel in different directions, then the trucks travel into each other, which would cause the collision.

While in the case of the airplanes more directions exists, so there isn't (necessarily) a collision.

Henry wants to center a towel rack on a wall that is 76.8 inches long. How much space will be between the end of the wall and th
ArbitrLikvidat [17]

The space between the end of the wall and the towel rack will be <u>9.2 inches</u>.

<h3>What is space?</h3>

Space is the relative position of objects at a distance from one another.

In this instance, space refers to the empty area at each end of the towel rack.

<h3>Data and Calculations:</h3>

The length of the towel rack = 58.4 inches

The length of the wall = 76.8 inches

The difference between the lengths of rack and wall = 18.4 inches (76.8 - 58.4)

Since Henry wants the towel rack to be centered, the space between the end of the wall and the towel rack will be <u>9.2 inches</u> (18.4/2).

Thus, the space between the end of the wall and the towel rack will be <u>9.2 inches</u>.
