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? Let's think step by step and output the final answer after "####".

The Saturday morning exodus out of the park comprised 4*2880 = <<4*2880=11520>>11520 elephants
This means that after the exodus, the park was left with 30000 - 11520 = <<30000-11520=18480>>18480 elephants
Since the final number of elephants was 28,980, the new elephants that entered were 28980 - 18480 = <<28980-18480=10500>>10500
The rate at which the new elephants entered the park was therefore 10500/7 = <<10500/7=1500>>1500 elephants/hour
