Total: 62

Solution:

Concept:

Use proportional reasoning to find the distance covered from the money spent on petrol.

Explanation:

First, find how many litres of petrol can be bought with ₦900.00.

Since 1 litre costs ₦63.00, the number of litres is:

\frac{900}{63} = 14.2857 \text{ litres}

The car travels 14 km on 1 litre.

Therefore, the total distance covered is:

14.2857 \times 14 = 200 \text{ km}

Answer:
