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:

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