Jacob rode his bicycle 144 miles in 9 weeks, riding the same distance each week. Lesley rode her bicycle 84 miles in 6 weeks, riding the same distance each week. How many more miles did Jacob ride his bicycle than Lesley per week they rode?

Answer 1

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

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 =

`=\frac{\text{Total number of miles}}{\text{Number of distance}}\\\\=(144)/(9)\\\\=16\text{ miles per week}`

Lesley rode her bicycle 84 miles in 6 weeks.

Number of miles rode in 1 week by Lesley =

`=\frac{\text{Total number of miles}}{\text{Number of distance}}\\\\=(84)/(6)\\\\=14\text{ miles per week}`

Thus, Jacob rode his bicycle more than Lesley by

`16-14\\=2\text{ miles per week}`

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