Final answer:
If a star rises 4 minutes earlier each day, after 60 days, it will be observable 4 hours earlier, changing the observation time from 10:30 p.m. to 6:30 p.m. For a population doubling every 10 minutes, by 6:00, it would have multiplied many times over.
Step-by-step explanation:
Based on the provided information, when something happens at 6:00 on April 11th would depend on the context. In one scenario, for a star that rises 4 minutes earlier each day, after two months (or 60 days), it will rise 240 minutes (4 hours) earlier. If it was initially observed at 10:30 p.m., after two months, it would then be visible at 6:30 p.m. instead.
In another case related to population growth, if a population in a jar doubles every 10 minutes and the initial jar is filled at 12:00, then by 6:00, numerous doublings would have occurred, resulting in a significant increase in the population, assuming the population continues to have the resources and space required for growth.
The growth would follow a geometric progression where each step represents a doubling of the population.
