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

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.
