The formula of the pursuit problem:
1, speed difference × catch-up time = distance difference.
2. Distance difference ÷ speed difference = catching up time (catching up in the same direction).
3, speed difference = distance difference, hurry.
4. How far can A go? Passing distance = the distance to catch up with the time difference.
Extended data
Are two objects in the same place? The chasing and meeting problems involved in moving on straight lines or closed figures are usually classified as chasing problems. This kind is often found in exams. ? Generally divided into two types:? Which one is double? Catch up, double? Encounter this kind of problem? Simple; ? How many kinds are there? Catch up, more? Satisfied, this is more difficult.
According to the question, are the two objects in the same place? The problems of' chasing, meeting and colliding' involved in linear motion are usually classified as chasing problems. Speed difference × catching up time = catching up distance, distance difference ÷ speed difference = catching up time (catching up in the same direction).
