Question

The second class railway fare for 240 km of Journey is Rs 15.00. What would be the fare for a journey of 139.2 km?

Answer 1

Let Rs x be the fare for a journey of 139.2 km.

Distance (in km)	240	139.2
Fare (in Rs.)	15	x

\[\text{ Since the distance travelled and the fare are in direct variation, we have: }  \]
\[\frac{240}{139 . 2} = \frac{15}{x}\]
\[ \Rightarrow 240 \times x = 15 \times 139 . 2\]
\[ \Rightarrow x = \frac{15 \times 139 . 2}{240}\]
\[ = \frac{2088}{240}\]
\[ = 8 . 7\]
\[\text{ Thus, the fare for a journey of 139 . 2 km will be Rs }  8 . 70 .\]
