A car's petrol consumption is 10,5 km per litre. Calculate the cost of a journey from Pretoria to Kroonstad, a distance of 231 km, if the cost of a litre petrol is R10, 70
To calculate the cost of the journey, we first need to determine how many liters of petrol will be consumed.
Given that the car's petrol consumption is 10.5 km per litre and the distance of the journey is 231 km, we can calculate the number of liters required as follows:
231 km / 10.5 km per litre = 22 liters
The cost of a liter of petrol is given as R10.70. Therefore, the total cost of the journey will be:
22 liters * R10.70 per liter = R235.40
To calculate the cost of the journey, we need to calculate the number of liters of petrol required and multiply it by the cost per liter.
Step 1: Calculate the number of liters of petrol required
The petrol consumption is given as 10.5 km per liter.
So, for a distance of 231 km, the number of liters required can be calculated by dividing the distance by the petrol consumption:
231 km / 10.5 km per liter = 22 liters (rounded to the nearest whole number)
Step 2: Calculate the cost of the journey
The cost of a liter of petrol is given as R10.70.
To calculate the cost of the journey, we multiply the number of liters required by the cost per liter:
22 liters * R10.70 per liter = R235.40
Therefore, the cost of the journey from Pretoria to Kroonstad, a distance of 231 km, is R235.40.
To calculate the cost of the journey, we need to determine how many liters of petrol are needed for the distance and then multiply it by the cost per liter.
First, we calculate the total liters required for the journey:
Liters of petrol = distance / petrol consumption = 231 km / 10.5 km per litre = 22 litres
Now, we can calculate the cost of the journey by multiplying the number of liters by the cost per liter:
Cost of the journey = liters of petrol * cost per liter = 22 litres * R10.70 per litre = R235.40
Therefore, the cost of the journey from Pretoria to Kroonstad, with a distance of 231 km and a petrol consumption rate of 10.5 km per litre, is R235.40.
