, QUESTION 1
1.1. A tractor travels 90 kilometers on 18 liters of fuel. How much fuel will it
need to travel 130 kilometers? Round off your answer to 2 decimal places.
Distance = 90 km
Fuel used = 18 liters
Fuel consumption per km = 18 ÷ 90 = 0.2 liters/km
Fuel needed for 130 km = 130 × 0.2 = 26.00 liters
1.2. 7 kg of tomatoes cost R 56,63. How much are you going to pay for 10 kg of
tomatoes?
Cost per kg = R56,63 ÷ 7
= R8,09 per kg
Cost for 10 kg = R8,09 × 10
= R80,90
1.3. If 30 men can build a wall of a shopping centre in 20 days, how long will it
take 25 men to build the exact same wall?
Total man-days required to build the wall
= 30 men × 20 days
= 600 man-days
Days 25 men will take to complete 600 man-days of work

, = 600 man-days ÷ 25 men
= 24 days
