WHat?? :O

[BornToBeGangsta 38]

Btw, your compass is wrong :P

East and West are the wrong way around :P

Uh... Isn't school enough pain already?? Dont make forum pain too please :p

ok i know it

 hypotenuse = base square + height square

5 square + 4 square = 25+16 = 41

root of 41 = 7 

therefore 7 km

really it's both physics and maths

Your right however displacement is a vector (something which can only be described by stating its direction aswell as its magnitude) so you need a direction. The direction could be found by using trigonometry and then using the 'compass' to state the direction. You have scored 1 point out of 2. Well done!

This is painful  :blink:

the root of 41 isn't 7 :P (root of 49 = 7)

[akashrox_re-born 281]

the root of 41 isn't 7 :P (root of 49 = 7)

what?

root of 41 is 7

49 is not a perfect square  :P  :P  :P  :P
