Respuesta :

Answer:

a. 4.67 dollars per hour

b. 0.43 minutes per page

Explanation:

Part a.

To know the cost per hour of bike use, we need to divide the total cost by the number of hours, so:

[tex]\frac{Cost}{Hours}=\frac{\text{ \$42}}{9\text{ hours}}=\text{ \$4.67 per hour}[/tex]

So, the cost is 4.67 dollars per hour

Part b.

In the same way, the number of minutes per page can be calculated as the division of the number of minutes by the number of pages, so:

[tex]\frac{\text{ Minutes}}{Pages}=\frac{6\text{ minutes}}{14\text{ pages}}=0.43\text{ minutes per page}[/tex]

So, it takes 0.43 minutes per page.
