Question

14.A taxi charges Rs.20 for the first kilometre and @.12 per km for
subsequent distance covered. Taking the total distance covered as x km
and total fare Rs. y, write a linear equation depicting the relation between
x and y. Find the taxi charges for covering: (a) 12 km and (b) 20 km.​

Answer 1

Answer:

Step-by-step explanation:

Answer:

y = 12x + 8

Step-by-step explanation:

Given that it costs Rs. 20 for the first km and Rs. 12 per km for every subsequent km.

So It is also given that, Distance covered is x and Total Fare is Rs. y

Linear Equation according to the question would be:

Total Distance = x

Rate for first km is 12. So Rate for remaining distance is ?

⇒ Remaining Distance = ( x - 1 )

⇒ Rate = 12 ( x - 1) = 12x - 12

Total Fare for the whole distance is Rs. y

⇒ y = 12x -12 + 20

⇒ y = 12x + 8

This is the required equation.

Hope it helped !!

Answer 2

Answer:

Thus ,(x=20⇒y=248) i.e., when distance covered is 20 km then the taxi -fare is . Rs 248
