Taro and Jiro play a game around the pond.
Taro turns around the pond in the clockwise direction.
It takes 12 minutes for one round by walking.
Jiro turns around the pond in the counterclockwise direction.
The speed along which Taro walks is 5/4 times the speed along which Jiro walks.
Two persons begin to walk at the same time from the same point. When they meet, they will play a janken (scissors-paper-rock) to decide winning and losing.
The person who won walks as it is and the person who lost hops forward in a squatting position (bunny hops) from there.
The speed of hopping is 3/4 times the walking speed of each person. The time concerning janken shall not be considered.
(1) In how many minutes from start walking is it that two persons meet for the first time?
(2) In two cases of how many minutes after meeting with the 1st time are there that two persons meet with the 2nd time?
