B] find the quantity of petrol required to cover 100 km. ​

Answer 1

${\tt{\red{\underline{\underline{\huge{ANSWER}}}}}}$

A) 52.5 km is distance it can cover using 3.5L of petrol.

B) 100/15 liers of petrol is required to cover 100km

Step-by-step explanation:

Given

• A car covers 15km using 1 litre of petrol.

To Find

• A) Distance covered using 3.5L of petrol

• B) The quantity of petrol required to cover 100km.

Solution

A) To find the distance covered using 3.5L of petrol

We have to multiply the the distance traveled in 1 liter with 3.5L.

15 × 3.5 = 52.5 km

☆_____________________________☆

B) [Observe the table that I have given]

In 1 liters Distance Travelled = 15km

Let the quantity of petrol used in 100 km be x

$\frac{1}{15} = \frac{x}{100}$

15x = 100 × 1 [Cross Multiplication]

x = $\frac{100}{15}$

So, 100/15 liters of petrol is required to cover 100km.
