Answer 1

Step-by-step explanation:

✷ Given :

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

\implies\dfrac{240}{139.2}=\dfrac{15}{x}

✷ Now we have to do cross

multiplication.

Then we get,

\implies240\times x=139.2\times15\\\\\\\\\implies x=\dfrac{139.2\times15}{240}\\\\\\\\\implies x=\dfrac{139.2\times1}{16}\\\\\\\\\\\implies \bold{\Huge{\boxed{x=8.7}}}

✷ Therefore Rs. 8.7 would be the

fare for a journey of 139.2 Km.
