A man goes 20 m due west and then 15 m due North. How far it from the starting point?
Answers
In the above Question , the following information is given -
A man goes 20 m due west and then 15 m due North.
To find -
Find his distance from the starting point.
Solution -
See the above attached image .
Here , the man moves 20 m due west and then 15 m due North.
So , his net displacement is due north - west .
Required Displacement can be calculated by Pythagoras theorem -
AC = √ ( AB )² + ( BC )²
=> AC = √ ( 15 )² + ( 20 )²
=> AC = √ ( 225 + 400 )
=> AC = √625
=> AC = 25 m .
Thus , he is 25 m far away from the starting point .
This is the required answer .
______________________________________
distance b/w starting point =(20*20)*+(25*25)=625
as we know 625 Is a square of 25 Therefore, distance from starting point is 25m
hope it will help u!!!!
