To find out how long each chore took, we need to calculate the difference between the start time and the finish time. We can do this by counting up the minutes.
1. Clean her room: 3:23 p.m. – 3:58 p.m.
* The hour stays the same (3 o'clock).
* We just need to find the difference in minutes: $58 - 23$.
* $8 - 3 = 5$
* $5 - 2 = 3$
* So, it took
35 minutes.
2. Homework: 6:12 p.m. – 6:34 p.m.
* The hour stays the same (6 o'clock).
* Find the difference in minutes: $34 - 12$.
* $4 - 2 = 2$
* $3 - 1 = 2$
* So, it took
22 minutes.
3. Make breakfast: 7:26 a.m. – 7:35 a.m.
* The hour stays the same (7 o'clock).
* Find the difference in minutes: $35 - 26$.
* Since 5 is smaller than 6, we can count up from 26 to 35.
* $26 + 4 = 30$
* $30 + 5 = 35$
* $4 + 5 = 9$
* So, it took
9 minutes.
4. Wash dishes: 5:35 p.m. – 5:52 p.m.
* The hour stays the same (5 o'clock).
* Find the difference in minutes: $52 - 35$.
* Let's count up from 35 to 52.
* $35 + 15 = 50$
* $50 + 2 = 52$
* $15 + 2 = 17$
* So, it took
17 minutes.
Final Answer:
* Clean her room:
35 minutes
* Homework:
22 minutes
* Make breakfast:
9 minutes
* Wash dishes:
17 minutes
