Answer:
42 pi inches
Step-by-step explanation:
Suppose the tip of the minute hand of a clock is two inches from the center of the clock. For each of the following durations, determine the distance traveled by the tip of the minute hand.
--------
r = 2 inches
The minute hand's tip travels 1 rev/hr = 2*pi*r inches = 4pi inch/hr
---------
Question 1: 15 minutes
15 mins = 1/4 hr
d = (1/4)*4pi = pi inches
-------------
and Question 2: 10 and a half hours.
d = 10.5*4pi = 42pi inches
