Let the number of times she turns the pedal in one mile be x.
Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then
Therefore, she turns the pedal 500 times in one mile.
Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then
Therefore, she turns the pedal 500 times in one mile.
K = (F - 32) + 273.15
To cancel out the 5/9, you can either multiply everything by the denominator and divide it down, or multiply everything by the reciprocal of the fraction (. Multiplying by the reciprocal is definitely easier if you can use a calculator:
K = (F - 32) + 491.67
Subtract 491.67 from both sides:
K - 491.67 = F - 32
Finish off by adding 32 to both sides:
K - 459.67 = F
Therefore, F = K - 459.67.
Hope this helps! :)
