|✷ Here is direct variation, So,

Fare for 240 km of journey is in rupees 15✷ To find : What would be the fare of journey of 139.2 km.

| Distance | Cost || 240 Km | Rs. 15 || 139.2 Km | Rs. x |

✷ Here is direct variation, So, According to the question

$\frac{240}{139.2} = \frac{15}{x}$

✷ Now we have to do cross multiplication.Then we get,

⟹240×x=139.2×15⟹x= 240139.2×15

⟹

$x = \frac{139.2}{15}$

$x = \frac{139.2 \times 1}{16}$

⟹ x=8.7

⟹ x=8.7 ✷ Therefore Rs. 8.7 would be the fare for a journey of 139.2 Km.
