The problem presents a scenario involving two individuals, Leanna and Esin, who were born in May, with Leanna being born on a Monday and Esin on the following Tuesday. The key detail is that Leanna is precisely 180 seconds older than Esin. To solve this, we must consider the time span that covers the transition from Monday to Tuesday, which is from 11:57 p.m. on Monday to 12:00 a.m. on Tuesday. This three-minute period, equating to 180 seconds, is the critical window in which Leanna could have been born just before midnight on Monday, and Esin could have been born just after midnight on Tuesday.

Given this information, the possible times for their births could be 11:57 p.m. for Leanna and 12:00 a.m. for Esin; 11:58 p.m. for Leanna and 12:01 a.m. for Esin; or 11:59 p.m. for Leanna and 12:02 a.m. for Esin. The question requires converting between units of time, specifically from seconds to minutes, and understanding the continuity of time across days to determine the possible birth times of Leanna and Esin.
