Question

Satpal walks $\frac{2}{3}$ km from a place P, towards east and then from there $1\frac{5}{7}$ km towards west. Where will he be now from P?

Answer 1

Distance travelled by Satypal towards east is denoted by positive sign. While the distances towards west would be denoted by negative sign.

Distance travelled by Satpal from the point P
= $-1\frac{5}{7}+\frac{2}{3}$
= $\frac{-12}{7}+\frac{2}{3}$
= $\frac{-36+14}{21}$
= $\frac{-22}{21}$
= $-1\frac{1}{21}$

It means that Satpal is at a distance $1\frac{1}{21}$ Km towards west of P.
