Answer:

696 miles at the first day, and 174 miles at the second day.

Step-by-step explanation:

Given:

Richard and Linda enjoy visiting Hilton Head Island, South Carolina.

The distance from their home to Hilton Head is 870 miles.

So, the drive takes them 2 days.

<u>Richard and Linda travel four times as far the first day as they do the second day.</u>

Question asked:

How many miles do they travel each day?

Solution:

Let Richard and Linda traveled at the first day = $x\ miles$

Then Richard and Linda traveled at the second day will be = $4x\ miles$

Total distance from their home to Hilton Head = 870 miles

Traveled at the first day in miles + Traveled at the second day = 870

$4x+x=870\\ \\ 5x=870\\ \\ Dividing\ both\ sides\ by\ 5\\ \\ x=174\ miles$

By substituting the value:

Richard and Linda traveled at the first day = $x\ miles$ = 174 miles

Richard and Linda traveled at the second day will be = $4x\ miles$

$=4\times174=696\ miles$

Therefore, they traveled 696 miles at the first day and 174 miles at the second day.
