1. The problem states that Juliet read for an hour and 15 minutes, but the start time is not provided. Therefore, the elapsed time is 1 hour and 15 minutes, but the beginning and end times cannot be determined without the start time.
2. Carlos was supposed to wake up at 4:30 a.m., but he woke up at 7:05 a.m. The elapsed time is calculated by subtracting the intended wake-up time from the actual wake-up time: 7:05 - 4:30 = 2 hours and 35 minutes. Carlos overslept for 2 hours and 35 minutes.
3. Sandra started watching her movie at 2:16 and shut off the TV at 2:16. The elapsed time is 0 hours and 0 minutes.
4. Mom needs to be at work by 9:00 a.m. and it takes her 1 hour and 11 minutes to drive. To find the departure time, subtract the driving time from the arrival time: 9:00 - 1:11 = 7:49 a.m. Mom needs to leave the house at 7:49 a.m.
5. Candace spent 1 hour and 13 minutes making cupcakes and 45 minutes making a cake. The total time is 1 hour and 13 minutes + 45 minutes = 1 hour and 58 minutes.
