12 、At 8:08 AM, Xiaoming set off from home on a bicycle. 8 minutes later, his father set off on a motorcycle to catch up with him. He caught up with Xiaoming 4 kilometers away from home, then immediately returned home. After arriving home, he immediately turned around to catch Xiaoming again, and caught up with him again 8 kilometers away from home. What time was it then?
12.【Solution】Dad is 4 kilometers away from home. If he does not return, but instead stops for 8 minutes, and then continues to chase Xiaoming.

He should catch up with Xiaoming exactly at 4+4=8 (kilometers) away from home. This indicates that Dad, from 4 kilometers away from home, returns,

and then comes back to this point, using a total of 8 minutes, meaning Dad travels 8 kilometers in 8 minutes, thus Dad uses a total of 8+8=16 (minutes),

the second time he catches up with Xiaoming is at 8:32 (8+8+16=32)
