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

### Instruction:
Utopia National Park hosted 30,000 elephants on Friday night. The next morning, there was a 4-hour elephant exodus out of the park, at a constant rate of 2,880 elephants/hour. Over the next 7-hour period, new elephants entered the park at a constant rate. If the final number of elephants in the park was 28,980, at what rate did the new elephants enter the park?

### Response:
 Jumla ya tembo 2,880*4 = <<2880*4=11520>>11,520 walitoka hifadhini.
Hii inamaanisha kulikuwa na tembo 30,000 - 11,520 = <<30000-11520=18480>>18,480 waliobaki katika hifadhi.
Tembo wapya walioingia hifadhini katika kipindi cha masaa 7 kinachofuata walikuwa 18,480 - 28,980 = 10,500
Tembo wapya waliingia hifadhini kwa kasi ya 10,500/7 = <<10500/7=1500>>1,500 tembo/saa.
