4:00 p.m.
8:00 p.m.
9:00 a.m.
12:00 a.m.

Explanation:

Step1: Calculate arrival time in Denver's time

Flight leaves at 12:30 p.m. and takes 7.5 hours. So 12:30 p.m. + 7.5 hours = 8:00 p.m. (Denver time).

Step2: Adjust for Hawaii time

Denver is 4 hours ahead of Hawaii, so Hawaii time is Denver time - 4 hours. 8:00 p.m. - 4 hours = 4:00 p.m.? Wait, no, wait. Wait, if Denver is ahead, Hawaii is behind. Wait, let's re - calculate. Wait, 12:30 p.m. (Denver) + 7.5 hours flight time = 8:00 p.m. (Denver). Now, since Hawaii is 4 hours behind Denver, we subtract 4 hours from 8:00 p.m. 8 - 4 = 4? No, that can't be right. Wait, maybe I messed up the direction. Wait, the problem says "Keenan's home in Denver is four hours ahead of Hawaii". So Hawaii time is Denver time minus 4 hours. Wait, but let's do it step by step.

Wait, departure time: 12:30 p.m. (Denver time). Flight duration: 7.5 hours. So arrival in Denver time: 12:30 + 7:30 = 20:00 (8:00 p.m.). Now, Hawaii is 4 hours behind Denver, so Hawaii time is 20:00 - 4:00 = 16:00? No, 16:00 is 4:00 p.m. But that's one of the options. Wait, but let's check again. Wait, maybe I made a mistake. Wait, 12:30 p.m. plus 7.5 hours: 12.5 + 7.5 = 20 (8:00 p.m. Denver). Then, since Hawaii is 4 hours behind, 8 - 4 = 4 p.m. Hawaii time? But that's option A. But wait, maybe the other way. Wait, maybe the flight is going from Denver to Hawaii, so the time in Hawaii is less than Denver. Wait, but let's check the options. Wait, maybe my initial calculation is wrong. Wait, 12:30 p.m. + 7.5 hours is 8:00 p.m. Denver. Then, Hawaii is 4 hours behind, so 8 - 4 = 4 p.m. Hawaii. But option A is 4:00 p.m. But let's check the options again. Wait, the options are 4:00 p.m., 8:00 p.m., 9:00 a.m., 12:00 a.m.

Wait, maybe I messed up the time zone direction. Wait, if Denver is ahead, Hawaii is behind. So when it's 8:00 p.m. in Denver, it's 4:00 p.m. in Hawaii? But that seems off. Wait, no, maybe the flight is crossing time zones, so the arrival time in Hawaii is calculated as departure time (Hawaii time) + flight time? Wait, no, departure is in Denver. Let's think of it as:

Departure time: 12:30 p.m. (Denver) = 8:30 a.m. (Hawaii, since Denver is 4 hours ahead, so Hawaii is 4 hours behind, so 12:30 - 4:00 = 8:30 a.m. Hawaii time). Then, flight duration is 7.5 hours. So arrival time in Hawaii: 8:30 a.m. + 7.5 hours = 16:00 (4:00 p.m.) Hawaii time. Ah, that's the same result. So the answer should be 4:00 p.m.

Answer:

A. 4:00 p.m.
