A man is bicycling to a train station twelve miles away and wants to catch a train. He has one and a half hours. The road is divided into three segments:

1. The first four miles are uphill, and he has to walk this part, which he estimates will take one hour.
   
2. The next four miles are downhill, and he can bike at twelve miles per hour on this segment.

3. The final four miles are on flat terrain, and he can bike at eight miles per hour on this segment.

He believes his average speed will be eight miles per hour, so he thinks he can reach the station on time.

Is the cyclist's reasoning correct?
