There is a wonderful math problem that seems to say that dogs run back and forth, and then ask how many meters they have run.
Is this the problem?

AB is 2 kilometers apart. Party A and Party B set out from two opposite places at the same time. There is a puppy running back and forth in the middle. The puppy and Party A set out at the same time, and Party B set out at the same time. When the dog meets Party B, Party A turns to Party B. The speed of the dog is12km/h, that of Party A is 4km/h, and that of Party B is 2km/h.. How many kilometers did the puppy run when A and B met?
