Answer:
He walked Ms. Evans' dog 3.89 miles.
Step-by-step explanation:
From the information provided, you know that the total distance that he walked both dogs is 17.5 miles, which can be expressed as:
x+y=17.5, where:
x is the distance he walked Mr. Jackson's dog
y is the distance he walked Ms. Evans' dog
Also, the statement indicates that he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog and you can write the following equation:
x=3.5y
Now, you can replace x=3.5y in the first formula and solve for y to find how far he walked Ms. Evans' dog:
3.5y+y=17.5
4.5y=17.5
y=17.5/4.5
y=3.89
According to this, the answer is that he walked Ms. Evans' dog 3.89 miles.
