Sum

A man goes 18 m due east and then 24 m due north. Find the distance of his current position from the starting point?

Advertisements

Solution

Let the initial position of the man be “O” and his final position be “B”.

By Pythagoras theorem

In the right ∆OAB,

OB2 = OA2 + AB2

= 182 + 242

= 324 + 576 = 900

OB = `sqrt(900)` = 30

The distance of his current position is 30 m

  Is there an error in this question or solution?
