Question

a car can cover a distance of 522km in 36 liters of petrol.how far can it traver with 14liters of petrol?​

Answer 1

Answer:

• 203 Kilometres

Step-by-step explanation:

Given:-

• Distance covered by car in 36 litres = 522 km

To Find:-

• Distance travelled by car in 14 litres petrol.

Solution:-

Firstly we calculate the distance travelled by the car in 1 litres of petrol.

→ Distance covered by car in 1 litres = Total Distance/total petrol consume.

Substitute the value we get

→ Distance covered by car in 1 litres = 522/36

→ Distance covered by car in 1 litres = 14.5 km

Now, calculating the distance covered by car in 14 litres of petrol.

→ Distance covered by car in 14 litres petrol = 14.5×14

→ Distance covered by car in 14 litres petrol = 203 km

• Hence, the distance covered by the car in 14 litres petrol is 203 kilometers.

Answer 2

Answer:

Given :-

• Distance cover by car = 522 km
• Petrol taken = 36 litre

To Find :-

• Distance covered by petrol in 14 litre

Solution :-

We can solve it by 2 method

Arthimetical method

$\tt \: Distance \: cover \: by \: car \: in \: 1 \: l= \dfrac{522}{36}$

$\tt \: Distance \: covered \: by \: car \: in \: 1 \: l= 14.5 \: km$

$\tt \: Distance \: cover \: by \: car \: in \: 14 \: l = 14.5 \times 14$

$\tt \: Distance \: cover \: by \: car \: in \: 14 \: l = 203 \: km$

Proportional Method

Let the distance be x

$\tt \: Distance \ratio \: Petro l$

$\tt \: 522 \ratio \: 36 = x \ratio \: 14$

$\tt \: \dfrac{522}{36} = \dfrac{x}{14}$

By cross multiplication

$\tt \: 522 \times 14 = x \times 36$

$\tt \: 7308 = 36x$

$\tt \: x = \dfrac{7308}{36}$

$\tt \: x = 203$
