Question

Toms red bicycle travels 50 ft for every 3 pedal turns. how many pedal turns are needed to travel a mile(5820)

Answer 1

50 / 3 = 5280 / x......50 ft to 3 turns = 5280 ft to x turns
cross multiply because this is a proportion
(50)(x) = (3)(5280)
50x = 15840
x = 15840/50
x = 316.8 pedal turns

Answer 2

Divide 50 with 3

50/3 = 16.67 (rounded)

one pedal = 16.67 ft

Divide 16.67 with 5820

5820/16.67 = 349.13

~ 350 pedals are needed

hope this helps
