$\tt\red{A}\tt\blue{N}\tt\orange{S}\tt\purple{W}\tt\green{E}\tt\pink{R} \tt\blue{::}$

$\tt \red{15.7km} = 1l \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \tt \blue\implies\tt \red{380.725km} = \frac{380725}{1000} \times \frac{10}{57} \\ \\ \tt \blue\implies\tt \red{380.725km} = \frac{380725 \times 10}{1000 \times 157} \\ \\ \tt \blue\implies\tt \red{380.725km} = \frac{3807250}{157000} \: \: \: \: \: \: \: \: \\ \\ \tt \blue\implies\tt \red{380.725km} = \mathfrak\green{24.5l}\: \: \: \: \: \:$

Answer 2

Answer:

24.25 litres

Step-by-step explanation:

15.7 km = 15700 m

380 km 725 m = 380725 m

Let x be the amount of petrol needed to cover 380725 m.

If 1 L gets us 15700m then

x = 380725/15700

x = 24.25 L
