<PRE><B>Question 1139429</B>
 The chain wheel of Emma’s bicycle has a radius
of 3.5 inches. The rear gear has a radius of 1.75 inches, and the
back tire has a radius of 12 inches. If Emma pedals for 150 revo-
lutions of the chain wheel, how far will she travel? Round to the
nearest foot.
-------
3.5/1.75 = 2, so the wheel makes x*150 = 300 revolutions.
----
Circumference of the tire = 2pi*r = 24pi inches = 2pi feet.
Distance = 600*pi feet
