Question

# A car needs 33 litres of petrol to cover a distance of 363 km. Petrol costs · 78 per litre. How much would one spend on a journey of 407 km by car?

Hint:

**Hint:**

Unitary method: The unitary method is a method in which we find the value of a unit and then the value of a required number of units. For example, If 10 apples cost is 100 rupees, 1 apple will cost 10 rupees and if we are asked to find the cost of 100 apples, we can find it by multiplying 100 with cost of 1 apple.

## The correct answer is: 407 km journey

### Step 1 of 2:

It is given that the car needs 33 litres of petrol to cover a distance of 363 km.

So, Petrol needed for 363 km of distance = 33 litres

Petrol needed for 1 km of distance = litres = litres

Step 2 of 2:

Now, Petrol needed for 407 km of distance = = 37 litres

Cost of 1 litre petrol = Rs.78

Cost of 37 litres petrol = 78 37 = Rs.2886

Final Answer:

Hence, we need to spend Rs.2886 for a 407 km journey.
