Respuesta :

Answer:

Jacob rode his bicycle 2 miles per week more than Lesley per week.  

Step-by-step explanation:

We are given the following in the questions:

Jacob rode his bicycle 144 miles in 9 weeks.

Number of miles rode in 1 week by Jacob =

[tex]=\dfrac{\text{Total number of miles}}{\text{Number of distance}}\\\\=\dfrac{144}{9}\\\\=16\text{ miles per week}[/tex]

Lesley rode her bicycle 84 miles in 6 weeks.

Number of miles rode in 1 week by Lesley =

[tex]=\dfrac{\text{Total number of miles}}{\text{Number of distance}}\\\\=\dfrac{84}{6}\\\\=14\text{ miles per week}[/tex]

Thus, Jacob rode his bicycle more than Lesley by

[tex]16-14\\=2\text{ miles per week}[/tex]

Thus, Jacob rode his bicycle 2 miles per week more than Lesley per week.
