<PRE><B>Question 666017</B>
The circumference that is traced out by the
minute hand is {{{ 2*pi*18 = 36*pi }}}
The circumference traced out by the 
hour hand is {{{ 2*pi*12 = 24*pi }}}
-------------------
20 minutes is {{{ 20/60 = 1/3 }}} of the
circumference
{{{ (1/3)*36*pi = 37.692 }}}
{{{ (1/3)*24*pi = 25.128 }}}
The tip of the hour hand travels 37.7 inches in 20 min
The tip of the minute hand travels 25.13 inches in 20 min
