A workshop originally needed 8 hours to process 2,400 parts. After the technical transformation, it can process 5,600 parts of the same kind in the same time. After the technical transformation, how many more parts can be processed per hour than before the technical transformation (use two methods to solve)
某车间原加工2400个零件需8小时，技改后在同样的时间里可加工同种零件5600个，技改后每小时可比技改前多加工零件多少个(用两种方法解)
