## Table of Contents – A Child Went 90m Towards East (Problem Solved)

- A child went 90m towards east.

- He turned Right and went 20m.

- He turned right and after going 30m he reached his uncle’s house.

- From there he went 100m to his north.

- Distance how far he is from his starting point needed to figure out which has figured out in the solution below.

**Note: This question was asked in Competitive Examination (CSS) – 2021 General Science & Ability Q7 (A).**

## Important Points To Solve The Problem

Following things are needed to discuss here.

- Directions i.e. East, West, North and South.
- Distance he covered according to the map.
- Distance from starting point.

Following things are given.

- Child went 90m in the direction of East, first of all.
- Takes turn twice to his right before reaching uncle’s home and covers distance 20 and 30m respectively.
- Finally, he travels 100m in north from uncles home.

After drawing a picture (according to the given values), we can easily figure out the distance from the starting point by calculating the value of hypotenuse With the Help of Pythagoras theorem.

## To Find

Distance from starting point = ?

## Solution

Let suppose the distance from starting point = y

By using the Pythagoras theorem,

y^{2} = (80)^{2} + (60)^{2}

y^{2} = 6400 + 3600

y^{2} = 10,000

y = 100m

Distance from the starting point = 100m answer
