Worked Solution & Example Answer:The programme for the field events of an athletics meeting held on 12 February 2016 is shown in ANNEXURE B - NSC Mathematical Literacy - Question 2 - 2017 - Paper 1
Step 1
Determine the total time from the start of this meeting until the end of the last field event.
Answer
To calculate the total time for this meeting, we first need to establish the timeline. The last field event is set to finish at 18:15 and each event before is timed, making certain assumptions about breaks.
-
The last field event should not exceed 25 minutes for completion, hence:
- If the last field event finishes at 18:15, then it starts at:
-
A breakdown of the times shows:
- Start time: 14:00
- End time: 18:15
- Total duration from start to end: 4 hours and 15 minutes or 4.25 hours.
Step 2
Calculate the difference in mass between the javelins used by a 19-year-old boy and a 15-year-old boy.
Answer
Given the masses of the javelins used by both athletes, let's denote:
- Mass of the javelin used by the 19-year-old boy as 800 g.
- Mass of the javelin used by the 15-year-old boy as 600 g.
The difference in mass is calculated by:
Step 3
Determine Thabo's age (in years) and also indicate the time of his event.
Answer
Thabo was born in January 1999. To determine his age:
- The current date of the event is 12 February 2016.
- His age is calculated as:
Since his birthday in January has already passed by this date, Thabo's age remains 17 years. The time of his event was not explicitly provided but can be inferred as occurring during the timeline presented above.
