Question 1 (31 marks)

1.1. Fuel Calculation

A tractor travels 90 kilometers using 18 liters of fuel. To calculate how much fuel will be
required to travel 130 kilometers, we start by finding the fuel consumption rate.

Step 1: Calculate fuel consumption rate per kilometer

Fuel per km=1890=0.2 liters/km\text{Fuel per km} = \frac{18}{90} = 0.2 \text{
liters/km}Fuel per km=9018=0.2 liters/km

Step 2: Multiply rate by the new distance

Fuel for 130 km=130×0.2=26.00 liters\text{Fuel for 130 km} = 130 \times 0.2 = 26.00
\text{ liters}Fuel for 130 km=130×0.2=26.00 liters

Explanation: This calculation helps learners understand unit rates. First divide to find
how much fuel is used per 1 kilometer, then multiply by the new distance.

1.2. Tomato Cost Calculation

Given: 7 kg of tomatoes cost R56.63

Step 1: Determine the cost per kilogram

Cost per kg=56.637=R8.09\text{Cost per kg} = \frac{56.63}{7} =
R8.09Cost per kg=756.63=R8.09

Step 2: Calculate for 10 kg
