Question

The Cab fare in Bangaluru is Rs. 21 for the first kilometer and Rs. 14 per kilometer for subsequent
distance covered. If distance is represented as d, and fare is represented as f, find the linear equation for
this relationship.

Answer 1

f = 21 + 14(d - 1) for d >= 1

Answer 2

Answer:

When the total fare is represented as f and the total distance is d,

then f = (d – 1) x 14 + 21 x 1 = 14(d – 1) + 21.

Therefore, the equation here is solved as f = 14d – 14 + 21 = 14d + 7 = 2d + 1.

Hence, the final linear equation is f = 2d + 1.
