Answer

**2.1 Relationship between Petrol Consumed and Distance Travelled** The car travels 12.5 km per litre of petrol. So, the more litres consumed, the farther the car can go. --- **2.2 Litres Consumed for 12500 Metres** 12500 metres is 12.5 km. So, the car uses 1 litre of petrol to travel 12.5 km. --- **2.3 Litres Consumed to Travel 37 km** To travel 37 km, the car uses approximately 2.96 litres of petrol. --- **2.4 Distance Travelled with 8 Litres of Petrol** With 8 litres, the car can travel 100 km. --- **2.5 Determine the Values of A, B, and C** Cannot determine A, B, and C without more information. --- **2.6 Cost of Driving 100 km** It costs R180.00 to drive 100 km. --- **2.7 Cost of a Round Trip of 97 km Each Way** The total cost of petrol for the round trip is approximately R349.20.

Solution

**2.1 Relationship between Petrol Consumed and Distance Travelled** Since the car drives \(12.5~\mathrm{km}\) per litre of petrol, the distance travelled, \(d\) (in km), is directly proportional to the petrol consumed, \(L\) (in litres). This relation can be written as \[ d=12.5L \] or equivalently, if the distance is known, the petrol consumed is \[ L=\frac{d}{12.5}. \] --- **2.2 Litres Consumed for 12500 Metres** First convert 12500 metres to kilometres: \[ 12500~\mathrm{m} = 12.5~\mathrm{km}. \] Using the relationship, the litres consumed are \[ L=\frac{12.5}{12.5}=1. \] Thus, \(1\) litre of petrol is consumed. --- **2.3 Litres Consumed to Travel \(37~\mathrm{km}\)** Using the relation, \[ L=\frac{d}{12.5}=\frac{37}{12.5}. \] Simplify the fraction: \[ \frac{37}{12.5}=\frac{37}{12.5}=\frac{74}{25}\approx 2.96. \] So, approximately \(2.96\) litres of petrol are consumed. --- **2.4 Distance Travelled with 8 Litres of Petrol** Using the relation, \[ d=12.5\times 8=100~\mathrm{km}. \] So, \(100~\mathrm{km}\) is travelled. --- **2.5 Determine the Values of \(A\), \(B\), and \(C\)** The question asks for the values of - \(A\) (2.5.1), - \(B\) (2.5.2), and - \(C\) (2.5.3). However, without additional information or details from the table (since only the 12.5 km/litre relationship is given), there is insufficient data to separately determine \(A\), \(B\), and \(C\). --- **2.6 Cost of Driving \(100~\mathrm{km}\)** From part 2.4, we determined that \(8\) litres are needed for \(100~\mathrm{km}\). With the petrol price at R22.50 per litre, the cost is calculated as \[ \text{Cost}=8\times22.50=180.00. \] Thus, the cost is R180.00. --- **2.7 Cost of a Round Trip of \(97~\mathrm{km}\) Each Way** First, compute the total distance for the trip: \[ \text{Total distance}=97+97=194~\mathrm{km}. \] The petrol consumed is \[ L=\frac{194}{12.5}=15.52\text{ litres} \quad (\text{exactly } \frac{194}{12.5}\text{ litres}). \] The total cost is then \[ \text{Cost}=15.52\times22.50\approx349.20. \] Thus, the cost of petrol for the round trip is approximately R349.20.

When we look at the relationship between petrol consumption and distance traveled, we can see a straightforward pattern: as you consume more liters of petrol, you can cover greater distances. Specifically, Mr. Flynn's car can travel 12.5 km for every litre consumed, making calculations easy—just divide the distance by 12.5 to determine how much petrol is needed! To figure out how many liters of petrol are consumed when traveling 12,500 meters, simply convert meters to kilometers: \( 12,500 \text{ m} = 12.5 \text{ km} \). Since the car travels 12.5 km per litre, that means it consumes 1 liter for this distance! For traveling 37 km, you’d calculate \( 37 \text{ km} \div 12.5 \text{ km/litre} = 2.96 \text{ litres}\), rounding gives approximately 3 litres. Now for the distance when 8 litres are consumed, it’s \( 8 \text{ litres} \times 12.5 \text{ km/litre} = 100 \text{ km} \). ### Cost Calculations As for the driving cost for 100 km, multiplying the number of liters required (8 litres) by the price per litre (R22.50) gives you R180. For Mr. Flynn’s round trip of 97 km, he’ll need \( 97 \text{ km} \times 2 = 194 \text{ km}\): this means he’ll consume \( 194 \div 12.5 \approx 15.52 \) litres. Hence, the cost is about \( R349.20 \), calculated as \( 15.52 \text{ litres} \times R22.50 \text{ per litre} \). By putting simple calculations to work, Mr. Flynn can efficiently budget his petrol costs and keep his travels on track. 🚗💨
