Because one mile is equivalent to 5280 feet, set up a proportion where x is the number of pedal turns: 50/3=5280/x
Now, cross multiply and you will get 50x=15,840.
Finally, to solve for the number of pedal turns, or x, divide both sides by 50 and you get that your answer is 316.8 pedal turns

Hey You!

STEP 1:

1 mile = 5,280 ft.

STEP 2:

5,280/50 = 105.6

STEP 3:

105.6 × 3 = 316.8

So, 316.8 (You can round that to 317) pedal turns are needed to travel a mile.
