Question

A news boy starts his route by walking 400 m E, then 300 m N. find how far the boy is from his starting point. Use graphical and component meththod.​

Answer 1

Explanation:

he walks 400 m from starting point to east then walks 300 m to n so the ans will be 300+400=700 m

Answer 2

Answer:

500 M, 36.86

Explanation:

Why 500 M?

A) Graphical Method:

Use the formula:

R = √(x)²+(y)²

Solution:

R = $\sqrt{(300)^2+(400)^2$

R = 500

B) Component Method:

You can also simply use the Pythagorean theorem respectively because the given is 300 M and 400 M and so they are called relative lengths. And at the same time, there is no angle given whatsoever and so that makes up a right triangle which still gives you the answer of 500 M.
