Because they move with wind currents (which can be different at different altitudes). If they are going in opposite directions, they cannot be at the same altitude. If they were at the same altitude, they would be subject to the same winds, so could not be going in opposite directions.
To find the resultant velocity when combining two velocities going in opposite directions, you simply subtract the smaller velocity from the larger velocity. The direction of the resultant velocity will be in the direction of the larger velocity.
The resultant velocity is found by subtracting the smaller velocity from the larger one if they are in opposite directions. This is because the velocities are working against each other to some degree, resulting in a net velocity that is the difference between the two.
Antiparallel forces are forces that act in opposite directions along the same line of action. This means that the forces are equal in magnitude but opposite in direction. In a free-body diagram, antiparallel forces are typically represented using arrows pointing in opposite directions along a straight line.
A node in a standing wave has zero displacement because it is a point where two waves traveling in opposite directions interfere destructively, causing the amplitudes of the two waves to cancel each other out. This results in no net movement or displacement at the node.
Assuming the two forces are acting ON THE SAME OBJECT, you can subtract the two forces, to get the net force. Important: This does not apply to Newton's Third Law, since the forces act on DIFFERENT OBJECTS. I mention this because people tend to get this confused.
Hot air balloons are steered by changing altitude. The air currents are often going different directions at different altitudes, and by changing altitude you can get into an air current going the direction that you want to go. This isn't complete control like the steering on a car or airplane, you are still limited to the directions that the wind is going, but you have some control.
According to google maps, it is approximately 1,621 miles (~2,609 km) from Albuquerque, NM, to Winnipeg, MB, Canada. If you'd like directions, try going to www.google.com and typing 'Albuquerque to Winnipeg', then searching....then after you search, click 'Maps' at the VERY top of the results page.
To find the resultant velocity when combining two velocities going in opposite directions, you simply subtract the smaller velocity from the larger velocity. The direction of the resultant velocity will be in the direction of the larger velocity.

Uh...they were going in opposite directions?
yes
Start in the same point but are going in opposite directions
Is a solid yellow line to my left on the road means what
Because we can't see the image you're referring to, we can't give the answer to which ray is opposite to BA. However, we can help. Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. So, if there are two rays (BA and BC) with a common endpoint (B) going in different directions, they are called opposite rays.
Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
Never, since they are travelling in opposite directions.. . . but probably not the one the algebra book's authors intended....If you assume that "opposite directions" means the cars are travelling towards each other, their closing speed (i.e. relative speed) is 105 mph. That means they'll meet in 100/105 hours, or slightly more than 57 minutes.
On a road, a solid line divides lanes of traffic which are going in opposite directions. A line composed of dashes divides lanes of traffic going in the same direction.
