# Clocks

How long path will walk the end of the clock's minute-hand long 7 cm for 330 minutes? How long will walk in the same time hour-hand?

Correct result:

minute hand walk:  241.9 cm
minute hand walk:  20.2 cm

#### Solution:

$s_m = 2\pi \cdot \dfrac{ 330}{ 60 } \cdot 7 = 241.9 \ \text{cm}$
$s_h = 2\pi \cdot \dfrac{ 330}{12 \cdot 60} \cdot 7 = 20.2 \ \text{cm}$ Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
