A lorry uses diesel oil at the rate of 16km per litre If diesel oil costs 15k per litre how much would be spent on diesel oil for a journey of 480km
The lorry travels 16km per 1 litre of diesel oil.
For a journey of 480km, the lorry would need 480/16 = 30 litres of diesel oil.
If diesel oil costs 15k per litre, then for a journey of 480km, the total cost of diesel oil would be 30 litres x 15k = 450k.
Therefore, the total amount spent on diesel oil for a journey of 480km would be 450k.
