Question

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?

Answer 1

There are 476 pedal turn in one mile.

Explanation:

We are given the following in the question:

Ratio of pedal turns to rear-wheel turns =

`4:7`

Number of wheel turns in one mile = 833

Let x be the number of pedal turns.

Thus, we can write:

`(4)/(7)=(x)/(833)\\\\\Rightarrow x = (833* 4)/(7)\\\\\Rightarrow x = 476`

Thus, there are 476 pedal turn in one mile.
