The velocipede, or high wheel bicycle, was a predecessor to the modern bicycle. The main difference was that the front wheel was much larger
than the back wheel and riders had to climb on. In the diagram below,
the front wheel is 54 inches in diameter while the back wheel is 16
inches in diameter. How far does the bicycle travel in inches if its front
wheel completes 20 revolutions? Round to the nearest hundredth.
