Below is an instruction that describes a task. Write a response that appropriately completes the request in German. Please answer in German.

### Instruction:
 Jerry mows 8 acres of lawn each week. He mows ¾ of it with a riding mower that can cut 2 acres an hour. He mows the rest with a push mower that can cut 1 acre an hour. How long does Jerry mow each week?


### Response:
 With a riding mower, Jerry can mow 8 acres x ¾ = 6 acres per day.
At a rate of 2 acres per hour, he can mow 6 acres in 6 acres / 2 acres/hour = 3 hours.
With a push mower, Jerry can mow 8 acres x ¼ = 2 acres per day.
At a rate of 1 acre per hour, he can mow 2 acres in 2 acres / 1 acre/hour = 2 hours.
In total, Jerry spends 3 hours riding + 2 hours pushing = 5 hours mowing each week.
