Answer:

A. Eric rode 2 more miles per week than Kim rode

Step-by-step explanation:

Number of miles Kim rode bicycle in 9 weeks = 135 miles

Let x be the number of miles per week.

135miles => 9 weeks

x miles => 1 week

$x = \frac{135}{9}$

$x = 15$

Kim rode the bicycle 15 miles per week

Number of miles Eric rode bicycle in 6 weeks = 102 miles

Let x be the number of miles per week Eric rides the bicycle.

102 miles => 6 weeks

x miles => 1 week

$x = \frac{102}{6}$

$x = 17$

Kim rode the bicycle 17 miles per week

<em>Comparing the number of miles per week they rode, we would conclude that: "Eric rode 2 more miles per week than Kim rode".</em>
