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 advantageous because they provide a visual representation of routes. They clearly illustrate both distances and the possible stops one can encounter along the way. By presenting information succinctly, strip charts help travelers to quickly assess their journey and make informed decisions regarding the best paths to take.
Step 2
Step 3
Compare with the necessary calculations Jean's petrol cost for her trip from Harare.
Answer
To calculate Jean's petrol cost:
- Distance to Harare = 532 km + 446 km = 978 km
- Fuel consumption: 7.5 liters per 100 km
- Total liters needed: ( \frac{7.5}{100} \times 978 = 73.35 ) liters.
Cost calculation:
- Price of petrol on 23 February 2016 was R 891,20.
- Total cost: ( 73.35 \times 12,15 = R 891,20 )
On 2 March 2016, the price was R 840,59.
- Total cost for return trip: ( 73.35 \times 11,46 = R 840,59 )
Difference in price: ( R 891,20 - R 840,59 = R 50,61 )
Jean paid less on her return trip because of the decrease in petrol price.
Step 4
Do you think that petrol cost is the only cost that Jean considered for undertaking the trip from Johannesburg to Harare?
Answer
No, while petrol is a significant cost, there are other factors to consider that could impact the overall expenditure of the trip:
- Fees for traveling through toll plazas or toll ramps could add to her expenses.
- Border post fees may also incur additional costs when crossing into Zimbabwe.
