Janet and Judy were going to the movies. Janet showed up at Judy’s door at 7:45 PM. “ You’re 90 minutes late!” exclaimed Judy. Explain how you can determine at what time Janet was supposed to meet Judy.

Answer 1

To determine the time Janet was supposed to meet Judy, we need to subtract 90 minutes from the time of Janet's arrival.

Since Janet arrived at Judy's door at 7:45 PM and was 90 minutes late, we can subtract 90 minutes from 7:45 PM to find the original planned meeting time.

7:45 PM - 90 minutes = 6:15 PM

Therefore, Janet was supposed to meet Judy at 6:15 PM.
