If one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours.

• 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.

## 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 = ? A child went 90m towards East and then turned Right and went 20m. From uncle’s house he walked 100m. He is 100m away from his starting point.

## Solution

Let suppose the distance from starting point = y

By using the Pythagoras theorem,

y2 = (80)2 + (60)2

y2 = 6400 + 3600

y2 = 10,000

y = 100m

Distance from the starting point = 100m answer
