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

The distance from Pretoria to Bela-Bela (Warmbaths) is 105 kilometers.

The total distance Jean traveled to Harare is 978 kilometers.

Using her vehicle's consumption of 7.5 liters per 100 kilometers, the total liters used for the trip is:

ext{Liters used} = rac{7.5}{100} imes 978 = 73.35 ext{ liters}

Cost Calculation for the trip:

• On 23 February 2016, the petrol cost was R 891.20, calculated as follows:
  • $ext{Cost} = 73.35 imes 12.15 = R 891.20$
• On 2 March 2016, the petrol cost was R 840.59, calculated as:
  • $ext{Cost} = 73.35 imes 11.46 = R 840.59$

Difference in cost: $ext{Difference} = R 891.20 - R 840.59 = R 50.61$

Jean will need to consider these costs as well as additional factors, such as toll fees and possible variations in fuel prices along the route.

1. Fees for traveling through toll plazas or toll ramps - These can add significantly to the total cost of the journey, especially if multiple tolls are involved.
2. Border post fees - Costs incurred at border crossings need to be accounted for, as they can also impact the overall expense of the trip.
