Question

Rohit walks 80 m towards left and then turns right. How much distance should he walk now so that the minimum distance between the initial and final point is 100 m? ___

Answer 1

The minimum distance between the initial and final point is 100 m which forms the hypotenuse of a right-angled triangle with one of the sides as 80 m.

Hence, the distance Rohit walks after turning right = $\sqrt{{100}^2-{80}^2}m$

$=\sqrt{{60}^2}m$

$=60m$.
