Why is the distance difference divided by the speed difference equal to the meeting time in the meeting problem? Please ask the senior primary school math teacher to explain it in detail so that the students can understand it. Speed sum multiplied by meeting time equals meeting distance, meeting distance divided by meeting time equals speed sum, and meeting distance divided by speed sum equals meeting time.

In the encounter problem, distance difference = speed difference × time difference; Speed difference = distance difference ÷ time; Time = distance difference/speed difference. In the problem of encountering the midpoint, the distance from the midpoint is twice as fast as that from the midpoint. Meeting time = distance difference ÷ speed difference.

Extended data tracking problem

The chasing and meeting problems involved in the movement of two objects on the same straight line or closed figure are usually classified as chasing problems. This kind of problem often appears in exams, and it is a big kind of problem in travel.

encounter a problem

When many objects are close to each other, we usually find the time of meeting or the whole journey.

Tap water problem

The boat itself is dynamic, even if the water doesn't flow, it has its own speed, but in flowing water, it is either pushed by running water or by running water, so that the speed of the boat changes in running water, while bamboo rafts and others have no speed, and its speed is the speed of water.
