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

### Instruction:
 Heath alitumia wikendi yake kusaidia shambani kwa mjomba wake kupanda karoti. Aliweka safu 400 za karoti na kila safu ilikuwa na mimea 300. Alitumia mashine kufanya kupanda na ilimchukua masaa 20. Alipanda karoti ngapi kwa kila saa?


### Response:
 Heath alipanda safu 400 x mimea 300 = <<400*300=120000>>120,000 za karoti.
Alipanda karoti 120,000 katika masaa 20, au 120,000 / 20 = <<120000/20=6000>>6,000 mimea kwa kila saa.
