Question

The second class railway fare for 240 km of journey is 15.00. What would be the fare for a jou
of 139.2 km? Assume that the fare varies directly as the length of the journey​

Answer 1

Answer:

8.63 unit

Step-by-step explanation:

For 240 km the fare is 15.00 unit

For 1 km the fare will be (15/240) unit = 0.062 unit

For 139.2 km the fare will be (0.062 × 139.2) unit

= 8.63 unit

Answer 2

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

Distance ( in km ) 240 139.2

Fare ( in Rs. ) 15 x

Since, the distance traveled and the fare are in direct variation, we have:

$⇒ \frac{240}{139.2} = \frac{15}{x}$

$⇒  240×x=15×139.2$

$⇒x= \frac{15 \times 139.2}{240}$

$⇒x= \frac{2088}{240}$

$∴ x=8.7$

∴ The fare for a journey of 139.2km will be Rs.8.70.
