Question

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.

Answer 1

81.9 turns

Explanation:

100 yd = 36 × 100 in. = 3600 in.

C = πd

C = 3.14 × 14 in. = 43.96 in.

3600/43.96 = 81.9

Answer: 81.9 turns
