The time it takes for two objects moving toward each other to meet is determined by both the distance separating them and their speeds. When calculating the time until they converge, the equation used is:

Time = Distance / (Speed of Object 1 + Speed of Object 2)

This equation clearly shows that the key factors are the initial distance between the two objects and their respective velocities. The greater the distance, or the slower the objects are moving, the longer it will take for them to meet.

Weight, temperature, and height do not directly affect the meeting time in this context. While weight could influence acceleration for falling objects, it does not impact the relative speed in the simplified scenario of two bodies approaching one another in a vacuum. Similarly, environmental temperature and the physical height of the objects are irrelevant to the distance they need to cover or their speeds relative to one another. These factors do not play a role in determining the convergence time, making the first choice the comprehensive and accurate one.
