Answer :

Let's solve each question step by step:

  1. Ann's Piano Practice

    Ann practices for 20 minutes every day. Since there are 7 days in a week, the total weekly practice time is:

    [tex]20 \text{ minutes/day} \times 7 \text{ days} = 140 \text{ minutes}[/tex]

    To convert this into hours and minutes, note that 60 minutes is equal to 1 hour. So,

    [tex]140 \div 60 = 2 \text{ hours} \quad \text{with a remainder of} \quad 20 \text{ minutes}[/tex]

    Therefore, Ann practices a total of 140 minutes, which is the same as 2 hours and 20 minutes.

  2. Starla's Gymnastics Practice

    Starla practices 3 times a week for 45 minutes each time. Therefore, her total practice time is:

    [tex]3 \times 45 = 135 \text{ minutes}[/tex]

    Converting to hours:

    [tex]135 \div 60 = 2 \text{ hours} \quad \text{with a remainder of} \quad 15 \text{ minutes}[/tex]

    Starla practices for 135 minutes, which is the same as 2 hours and 15 minutes.

  3. Nick's Tennis Practice

    Nick practices 4 times a week, each session lasting 90 minutes. Thus his total practice time is:

    [tex]4 \times 90 = 360 \text{ minutes}[/tex]

    Converting to hours:

    [tex]360 \div 60 = 6 \text{ hours}[/tex]

    Nick practices for 360 minutes, which is exactly 6 hours.

  4. Liz's Singing Practice

    Liz practices twice a week for 50 minutes each time. So, her total practice time is:

    [tex]2 \times 50 = 100 \text{ minutes}[/tex]

    Converting to hours:

    [tex]100 \div 60 = 1 \text{ hour} \quad \text{with a remainder of} \quad 40 \text{ minutes}[/tex]

    Liz practices for 100 minutes, which is the same as 1 hour and 40 minutes.

  5. Max's Guitar Practice

    Max practices 4 times a week for 20 minutes each session. This means he practices for:

    [tex]4 \times 20 = 80 \text{ minutes}[/tex]

    Converting to hours:

    [tex]80 \div 60 = 1 \text{ hour} \quad \text{with a remainder of} \quad 20 \text{ minutes}[/tex]

    Max practices for 80 minutes, which is the same as 1 hour and 20 minutes.

  6. Harry's Weight Lifting

    Harry lifts weights 4 times each week for 30 minutes per session. His total weekly function time is:

    [tex]4 \times 30 = 120 \text{ minutes}[/tex]

    Converting to hours:

    [tex]120 \div 60 = 2 \text{ hours}[/tex]

    Harry lifts weights for 120 minutes, which is exactly 2 hours.
