Question

For the first kilometer, the fare is Rs. 5 and for the successive distance it is Rs. 2 per km. Taking distance covered as x and the total fare as Rs. y Write alinear equation.

Answer 1

if the total distance is x, then the remaining distance = x-1...

so, y = 5 + ( x-1) * 2

= 5 + 2x - 2

= 2x + 3.....

so if x = 1..

y = 2 + 3 = 5...

if x = 2..

y = 4 + 3 = 7....

if x = -1..

y = -2 + 3 = 1...

HOPE U UNDERSTAND...! :D

Answer 2

.let distance =X
total fair=y
according to question
for 1at km fair is rs5
for remaining it is rs2.

5(X-1)2=y
5X-3=y
X=0then y =3
is X=3then y=8
if X=-1then y=-2
