Step-by-step solution

7 steps
  1. Determine the start time of the Math lit period.

    The Math lit period started at the time shown on watch A, which is 12:45.

  2. Calculate the end time of the Math lit period.

    The duration of the period is 45 minutes.

    12:45+45 minutes=13:3012:45 + 45 \text{ minutes} = 13:30
  3. Calculate the start time of the next period.

    There is a 5-minute break after the period.

    13:30+5 minutes=13:3513:30 + 5 \text{ minutes} = 13:35
  4. Compare with Mr Matete's claim.

    Mr Matete stated the next period will start at 14:00. Our calculated start time for the next period is 13:35.
    Therefore, Mr Matete is incorrect.

  5. Determine Mr Nyamakazi's departure time.

    He departed at the time shown on watch A, which is 12:45.

  6. Calculate Mr Nyamakazi's actual arrival time in Botsabelo.

    Departure time: 12:45
    Travel duration: 34 minutes

    12:45+34 minutes12:45 + 34 \text{ minutes}

    To add the minutes: 45+34=7945 + 34 = 79 minutes.
    Since 60 minutes make 1 hour, 79 minutes is 1 hour and 19 minutes.
    Add 1 hour and 19 minutes to 12:00:

    12:00+1 hour 19 minutes=13:1912:00 + 1 \text{ hour } 19 \text{ minutes} = 13:19

    The calculated arrival time is 13:19.

  7. Compare with Mr Nyamakazi's claim.

    Mr Nyamakazi claimed he arrived at 13:12. Our calculated arrival time is 13:19.
    Therefore, Mr Nyamakazi is incorrect.
