Equator

Suppose that a tourist went on foot over the Globe Equator. How many meters more track made ​​his hat on his head as the shoes on your feet? The radius of the Earth is 6378 km, and the height of the tourist is 1.7 m.

Final Answer:

x =  10.7 m

Step-by-step explanation:

$$\begin{gathered} R=6378\text{km}\to \text{m}=6378\cdot 1000\text{m}=6378000\text{m} \\ v=1.7\text{m} \\ x=x_1-x_2 \\ x=2\pi (R+v)-2\pi R \\ x=2\pi \cdot v=2\cdot 3.1416\cdot 1.7=10.7\text{m} \end{gathered}$$
