Shane marched 3 m East and 6 m north. How far is he from his starting point. Round your answer to the nearest tenth.

The distance from his starting point is  6.7 m.

Step-by-step explanation:

Given:

Shane marched 3 m East and 6 m north.

Now, to get the distance from his starting point.

Let the distance from the starting point be

Now, to solve using pythagorean theorem:

Using square root on both sides we get:

So, the distance from the starting point nearest to tenth is 6.7 m.

Therefore, he is 6.7 m from his starting point.

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
