Jack has a grove with 4 trees by 5 trees.  It takes 6 minutes to clean each tree.  He gets help to clean the trees so it only takes half as long.  How many hours did he spend cleaning trees? Let's think step by step and output the final answer after "####".

There were 4*5=<<4*5=20>>20 trees to clean
So it took 20*6=<<20*6=120>>120 minutes
That is 120/60=<<120/60=2>>2 hours
So he spent 2/2=<<2/2=1>>1 hour cleaning
