PLEASE HELP: 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. (round to the nearest whole number)
