A penny-farthing is a bicycle with a very large front wheel and a much smaller back wheel. Penny-farthings were popular in the
1800s and were available in different sizes. If the front wheel of a penny-farthing has a diameter of 56 inches and the back wheel has a diameter of 14 inches, how many turns does the back wheel make when the penny-farthing travels 100 yards? Use 3.14 for pi.
