Question

A hiker leaves her camp in the morning. She walks 9 miles west then 10 miles north. Explain how you would find how far she has traveled from her camp.

Answer 1

Answer:

About 13.45 miles ( rounded )

Step-by-step explanation:

You would use the pythagorean theorem to solve this. ($a^{2}$+ $b^{2}$ = $c^{2}$)

$a^{2}$ would be one length of that triangle, we'll use 9.

$b^{2}$ would be the other length of that triangle, we'll use 10.

So, now you have to square both of them.

$9^{2}$ = 81 ( 9 x 9 )  $10^{2}$ = 100 ( 10 x 10 )

Which you will get 81 and 100. Then you add those two numbers together.

100 + 81 = 181

Now that you have 181, you have to square root 181.

$\sqrt{181}$

With that you should get 13.45 miles. (rounded)
