Question

1. rica is leaving her house at 5:30 p.m. to go to a dinner party. she is making spinach dip. the dip takes 10 minutes to prepare and then needs to refrigerate for 2 hours. what time should rica start making the spinach dip?

3:00 p.m.
4:30 p.m.
5:00 p.m.
3:20 p.m.

Explanation:

Step1: Calculate total time needed

The dip takes 10 minutes to prepare and 2 hours to refrigerate. Convert 2 hours to minutes: \(2\times60 = 120\) minutes. Total time: \(120 + 10=130\) minutes, or 2 hours and 10 minutes.

Step2: Subtract total time from leaving time

Rica leaves at 5:30 p.m. Subtract 2 hours and 10 minutes from 5:30 p.m.

• Subtract 2 hours from 5:30 p.m.: \(5:30 - 2:00 = 3:30\) p.m.
• Subtract 10 minutes from 3:30 p.m.: \(3:30 - 0:10 = 3:20\) p.m.

Answer:

3:20 p.m.
