Question

a car consumes 10 l petrol to cover a distance of 150 km.

(a) how much petrol will it consume for 366 km.

(b) how much distance will in cover in 2.5 of petrol.​

Answer 1

Answer:

7.5 kilometres

Step-by-step explanation:

10 litres petrol = 150 kilometres

2.5 litres petrol = x kilometres

By unitary method

Distance covered by 1 litre petrol = distance covered/ number of litres of petrol used

Distance covered by 1 litre petrol = 150/10

Distance covered by 1 litre petrol= 15 kilometres

Distance covered by 2.5 litre petrol = 2.5 × Distance covered by 1 litre petrol

Distance covered by 2.5 litre petrol = 2.5 × 15

Distance covered by 2.5 litre petrol = 37.5 kilometres

It will cover 37.5 kilometres with 2.5 litre petrol

Answer 2

10 L = 150 km

1 L = 15 km

and,

1 km =

$\frac{10}{150}$

1 km needed 1/15 L of petrol

Now ,

a) 366 km

=>

$\frac{1}{15} \times 366$

24.4 L of petrol...

Now ,

1 L = 15 km

2.5 L = 15 × 2.5

=> 37.5 km
