Worked Solution & Example Answer:3.1 "Strip charts is a very useful tool when travelling between two locations." Explain why strip charts is a useful tool - NSC Mathematical Literacy - Question 3 - 2016 - Paper 2
Step 1
Explain why strip charts is a useful tool.
Answer
Strip charts are useful as they visually represent specific routes, indicating particular paths that can be traversed between two locations. They also provide information regarding distances between places and highlight stopover points along the route, which can be essential for planning trips efficiently and effectively. Furthermore, they often display the shortest routes, which is advantageous for travelers looking to save time.
Step 2
How far is it from Pretoria to Bela-Bela (Warmbaths)?
Answer
The distance from Pretoria to Bela-Bela (Warmbaths) is calculated as follows:
- From Pretoria to Bela-Bela: 480 km
- Additional distance from Bela-Bela to an entry point in the route: 375 km.
Thus, the total distance is:
Total Distance = 480 km - 375 km = 105 km.
Step 3
Calculate Jean's petrol cost for the trip from Harare.
Answer
-
The total distance to Harare:
- 532 km + 446 km = 978 km
-
The vehicle's fuel consumption:
- 7.5 litres per 100 km implies:
- Total litres used = (7.5 / 100) * 978 = 73.35 litres.
-
Petrol costs on key dates (23 February and 2 March):
- On 23 February 2016, the cost was R 891.20.
- On 2 March 2016, the cost was R 840.59.
-
Cost difference:
- Difference in cost = R 891.20 - R 840.59 = R 50.61.
Step 4
Mention TWO other costs evident from the trip that Jean must also consider.
Answer
- Fees for traveling through toll plazas or toll ramps, which can add additional costs to her journey.
- Border post fees associated with crossing from South Africa into Zimbabwe, as these can vary based on the regulations in effect at the time of travel.
