Question

d(J,A) Find the distances with the help of the number line given in the image.

Answer 1

D(j, a) = 2 units in negative direction + 1 unit in

positive direction.

= 2 + 1

= 3 units

Answer 2

Solution :

D( J, A ) = D(O, A) - D(O, J)

= 1 - ( -2 )

= 1 + 2

= 3

Therefore ,

D( J,A) = 3
