Here are the solutions for the time problems on the worksheet.
First Clock (Top)
*
Current Time: The hour hand is on 8 and the minute hand is on 12. The time is
8:00.
*
In 3 hours: $8 + 3 = 11$. The time will be
11:00.
*
1 hour and 20 minutes ago: First, go back 1 hour from 8:00 to get 7:00. Then, go back 20 minutes. Since there are 60 minutes in an hour, $60 - 20 = 40$. The time was
6:40.
*
In 4 hours and 40 minutes: First, add 4 hours to 8:00 to get 12:00. Then, add 40 minutes. The time will be
12:40.
Second Clock
*
Current Time: The hour hand is past 8 and the minute hand is on 4 ($4 \times 5 = 20$). The time is
8:20.
*
In 2 hours and 20 minutes: Add 2 hours to 8:20 to get 10:20. Then add 20 minutes ($20 + 20 = 40$). The time will be
10:40.
*
4 hours ago: Subtract 4 hours from 8:20 ($8 - 4 = 4$). The time was
4:20.
*
In 3 hours and 40 minutes: Add 3 hours to 8:20 to get 11:20. Then add 40 minutes ($20 + 40 = 60$). Since 60 minutes makes a full hour, we move to the next hour. The time will be
12:00.
Third Clock
*
Current Time: The hour hand is on 9 and the minute hand is on 12. The time is
9:00.
*
In 1 hour and 20 minutes: Add 1 hour to 9:00 to get 10:00. Then add 20 minutes. The time will be
10:20.
*
2 hours and 40 minutes ago: Subtract 2 hours from 9:00 to get 7:00. Then subtract 40 minutes. $60 - 40 = 20$, so we go back to the previous hour. The time was
6:20.
*
In 4 hours: Add 4 hours to 9:00 ($9 + 4 = 13$). Since clocks go up to 12, this is
1:00.
Fourth Clock (Bottom)
*
Current Time: The hour hand is past 7 and the minute hand is on 4 ($4 \times 5 = 20$). The time is
7:20.
*
In 3 hours: Add 3 hours to 7:20 ($7 + 3 = 10$). The time will be
10:20.
*
2 hours and 20 minutes ago: Subtract 2 hours from 7:20 to get 5:20. Then subtract 20 minutes ($20 - 20 = 0$). The time was
5:00.
*
In 1 hour and 40 minutes: Add 1 hour to 7:20 to get 8:20. Then add 40 minutes ($20 + 40 = 60$). This adds another full hour. The time will be
9:00.
