Explanation

L = 14km, Cost L = #63, Dist. covered = #900= #900/#63 x 14km = 200kmTo find out how far the car can go with #900.00 worth of petrol, we can use the given information that the car uses one litre of petrol for every 14km and that one litre of petrol costs #63.00.First, let's find out how many liters of petrol can be bought with #900.00:Number of liters = Amount of money / Cost of one literNumber of liters = 900 / 63Number of liters = 14.29 (approximately)Now, we can find out how far the car can go with this amount of petrol:Distance = Number of liters * Distance covered by one literDistance = 14.29 * 14Distance ≈ 200.06 kmTherefore, the car can go approximately 200 km with #900.00 worth of petrol.
