D.) Eric rode 17 more miles per week than Kim rode

Answer 1

The correct answer is @, because Kim rode15 miles per week, and Eric rode 17 per week

Answer 2

Answer:

The answer is the option A

Eric rode $2$ more miles per week than Kim rode

Step-by-step explanation:

Step 1

Find the number of miles that Kim rode per week

Divide the total miles by the total weeks

so

$\frac{135}{9}\frac{miles}{weeks}= 15\frac{miles}{week}$

Step 2

Find the number of miles that Eric rode per week

Divide the total miles by the total weeks

so

$\frac{102}{6}\frac{miles}{weeks}= 17\frac{miles}{week}$

Step 3

Compare the unit rates

Kim $15\frac{miles}{week}$

Eric $17\frac{miles}{week}$

$17\frac{miles}{week}-15\frac{miles}{week}=2\frac{miles}{week}$

so

Eric rode $2$ more miles per week than Kim rode
