Answer 1

Answer:

from initial position Raju is 140m away

Answer 2

• Raju is 140 m far from his initial position .

Given :-

• Raju walks 80m towards south.
• Then ,turns to his right and walks 80 m .
• Then again turning to his left he walks for 60 m .
• He then turns to his left and walks for 80 m .

To Find :-

• How far is he from his initial position ?

Solution :- (Refer to image)

Let us assume that Raju starts from point A . So point A is the initial point .

Step 1) :-

• From point he walks 80 m towards south and say he reach at point B .
• AB = 80 m .

Step 2) :-

• From point B he turns to his right in west direction and walks for 80m and reach at point C .
• BC = 80 m .

Step 3) :-

• From point C he turns to his left in south direction and walks for 60m and reach at point D .
• CD = 60 m .

Step 4) :-

• From point D he turns to his left in east direction and walks for 80m and reach at point E .
• DE = 80 m .
• E = Final point .

from image we can see that,

→ CD = BE { As CB is equal to DE }

→ BE = 60 m

therefore,

→ AE = AB + BE

→ AE = 80 + 60

→ AE = 140 m (Ans.)

Hence, Raju is 140 m far from his initial position .
