Question

A van covers 432 km with 36 litres of diesel. How much distance would it cover with 25 litres of diesel?

Answer 1

Hint:
We are going to approach this problem by finding the distance that the van covers with 1 litre of diesel. Then we are going to multiply it by 25 to get the distance of the van that covers 25 litres of diesel.

Complete step-by-step answer:
It is given that the van covers 432 km with 36 litres of diesel.
So, Distance covered by van in 36 litres of diesel = 432km
At first, we are going to find the distance covered by a van with 1 litre of diesel.
We are going to find the distance covered by a van with 1 litre. For this, we are going to divide 432 by 36.
Distance covered by Van in 1 litre = $\dfrac{{432}}{{36}} = 12{\text{ km}}$
Now we found that the van covers 12 km with 1 litre of diesel.
Now we are going to multiply 12 by 25 so that we can find the distance covered by a van with 25 litres of diesel.
Distance covered by Van in 25 litres of diesel= $12 \times 25 = 300{\text{ km}}$
Hence we can conclude that the van will cover 300 km with 25 litres of diesel.

Note:
We clearly know that in 25 litres of diesel, a van will cover less distance than 432 km using 36 litres of diesel. So we can surely say that the distance that a van covers with 25 litres of diesel is less than the distance that a van covers with 36 litres of diesel. In this way, we can check the answer.
