In 2 seconds, the kangaroo mother makes three jumps, and the joey makes five jumps. The length of the mother kangaroo's jump is 6 meters, while the length of the joey's jump is three times less. The mother and joey are playing tag: the joey jumps ahead by 12 jumps, after which the mother starts to chase him, and he continues to jump. How long will it take for the mother to catch up?
In two seconds, the mother kangaroo makes 3 jumps, which means she jumps 9 jumps of the joey. Therefore, in two seconds, the distance between the mother and the joey decreases by 4 jumps of the joey. Initially, there were 12 jumps of the joey between them, so it will take the mother 6 seconds to catch up.

## Answer

In 6 seconds.
