Let the mother rabbit catch up with the rabbit after x seconds.

Meaning from the title: 6x = 3x +24

x=8A: The mother rabbit can catch up with the rabbit after 8 seconds.

Analysis: Because the rabbit is 24 meters away from the rabbit mother, and the rabbit mother runs x meters, the rabbit runs 3x+24m The result is that the rabbit mother catches up with the rabbit, and it finally stops in one place, so 3x +24 = 6x

That is, the results can be obtained.

If you don't understand something, ask again.

The distance between the mother rabbit and the baby rabbit is shortened by 3m per second, so it only takes eight seconds to catch up.

v mother rabbit - v rabbit = v shortened, t = s v shortened = 24 3 = 8 sec.

24/（6-3）=8

Answer: The mother rabbit can catch up with the rabbit after 8 seconds.

The difference between the mother rabbit and the baby rabbit is 3 meters per second (6 3 3), and the distance of 24 meters can catch up with (24 3 = 8) in just 8 seconds

If the distance is the same, the equation can be listed;

Set x seconds later to catch up with the rabbit.

6x=3x+24

Solution x=8

24 (6-3) = 8 (seconds).

If you are 24 meters apart, you need to use the speed difference to complete the run.

Set x seconds later, the mother rabbit will catch up.

So there are 6x-3x 24

Solution x=8
