# Equator

Suppose that 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 height of the tourist is 1.7 m.

Result

x =  10.7 m

#### Solution:

$x = x_1-x_2 = 2 \pi(R+1.7) - 2 \pi R = 2 \pi \cdot 1.7 = 10.7 \ \text{m}$
