Question

On Anne's bike, the ratio of pedal turns to real-wheel turns in second gear is 4 to 7. If her rear wheel turns 931 times per mile, how many times does she turn the pedal in one mile?

Answer 1

941

Explanation:

`(4)/(7)` =
`(x)/(931)` Cross multiply and solve for x

7x = 4(931)

7x = 6587 Divide both sides by 7

x = 941
