On Anne's bicycle, the ratio of pedal turns to rear-wheel turns in second gear is 4 to 7. If her rear wheel turns 833 times per mile, how many times does she turn the pedal in one mile?

Respuesta :

Answer:

There are 476 pedal turn in one mile.

Step-by-step explanation:

We are given the following in the question:

Ratio of pedal turns to rear-wheel turns =

[tex]4:7[/tex]

Number of wheel turns in one mile = 833

Let x be the number of pedal turns.

Thus, we can write:

[tex]\dfrac{4}{7}=\dfrac{x}{833}\\\\\Rightarrow x = \dfrac{833\times 4}{7}\\\\\Rightarrow x = 476[/tex]

Thus, there are 476 pedal turn in one mile.
