Question

1. jeannine is planning dinner and a movie with her partner. the movie they will see starts at 7:30 p.m., and they need at least an hour and a half to eat dinner. what is the latest time that they should arrive at a restaurant to eat dinner?

5:45 p.m.
6:00 p.m.
9:00 p.m.
6:30 p.m.

Explanation:

Step1: Convert 1.5 hours to minutes

1 hour = 60 minutes, so 0.5 hours = 30 minutes. Thus, 1.5 hours = 60 + 30 = 90 minutes.

Step2: Subtract 90 minutes from 7:30 p.m.

First, subtract 60 minutes (1 hour) from 7:30 p.m., we get 6:30 p.m. Then subtract another 30 minutes, we get 6:00 p.m.? Wait, no, wait. Wait, 7:30 p.m. minus 1 hour and 30 minutes. Let's do it step by step. 7:30 p.m. minus 1 hour is 6:30 p.m., then minus 30 minutes is 6:00 p.m.? Wait, no, that's wrong. Wait, 1 hour and a half is 90 minutes. 7:30 p.m. is 760 + 30 = 450 minutes. Subtract 90 minutes: 450 - 90 = 360 minutes. 360 minutes is 660 = 6:00 p.m.? Wait, but let's check again. Wait, the movie starts at 7:30 p.m., they need at least 1.5 hours to eat. So the latest time to arrive is 7:30 p.m. minus 1.5 hours. 7:30 minus 1 hour is 6:30, minus 30 minutes is 6:00. Wait, but the options include 6:00 p.m. But wait, maybe I made a mistake. Wait, 7:30 p.m. minus 1 hour and 30 minutes: 7:30 - 1:30 = 6:00. Yes, that's correct. So the latest time is 6:00 p.m. Wait, but let's check the options. The options are 5:45, 6:00, 9:00, 6:30. So 6:00 p.m. is an option. Wait, but wait, maybe I messed up. Wait, 7:30 p.m. minus 1 hour and 30 minutes: 7:30 - 1:30 = 6:00. So the latest time to arrive is 6:00 p.m. So the correct option is 6:00 p.m.

Wait, no, wait a second. Wait, maybe I made a mistake. Let's think again. If the movie starts at 7:30 p.m., and they need 1.5 hours to eat, then the latest time to start eating is 7:30 p.m. minus 1.5 hours, so the arrival time should be at least 1.5 hours before 7:30 p.m. So 7:30 p.m. minus 1 hour is 6:30 p.m., minus 30 minutes is 6:00 p.m. So yes, 6:00 p.m. is the latest time. So the correct option is 6:00 p.m.

Answer:

B. 6:00 p.m. (Wait, no, the options are not labeled A, B, etc. Wait, the options are:

• 5:45 p.m.

• 6:00 p.m.

• 9:00 p.m.

• 6:30 p.m.

So the correct one is 6:00 p.m. So the answer is 6:00 p.m. (the option with 6:00 p.m.))
