<p>In the figure above, two bikes are being pedaled in opposite directions around a circular track of a circumference= 120 feet. bike A is traveling 5 feet/sec in the counter clock wise direction and bike B is traveling 8 feet/sec in the clockwise direction. When bike B has completed exactly 600 revolutions, how many complete revolutions will bike A have made?</p>
<p>A. 180
B. 375
C. 475
D. 960
E .cant be determined</p>
<p>Answer: B </p>
<p>The diagram is basically a circle with A adjacent to B on on side and their about to circle around the track in opposite directions. Pretty self explanatory. My question is this: </p>
<p>How can a bigger wheel that takes up more distance per revolution make more revolutions than a smaller wheel? Since the time of both wheels is equal and B is traveling a larger distance, then the circumference of B is larger, thus fewer revolutions than A. Apparently wheels shape shift in Grubers world.</p>
