Answer 2

Answer:

Fare for journey of 80kms will be 120Rs.

Step-by-step explanation:

In this question,

We have been given that

Fare of a bus increases by Rs.10 for every 10kms.

Fare for the First 10kms is Rs.50

We need to find the Fare for the journey of 80Kms.

According to the question

Solving using A.P

Here a=50 , d=10 , and n=8

Using the formula we get,

$a_{n}\ =\ a+(n-1)d$

Putting the values we get,

$a_{n}\ =\ 50+(8-1)10$

$a_{n}\ =\ 50+(7)10$

$a_{n}\ =\ 70+50$

$a_{n}\ =\ 120$

Therefore, fare of journey of 80kms. will be 120Rs.
