John Rey and Charlotte are 220 feet apart when they start walking toward one another. They are walking at the same speed, so whenever John Rey travels some number of feet, Charlotte travels the same number of feet. Let 
x
 represent the number of feet John Rey has traveled since he started walking toward Charlotte.

Write an expression in terms of 
x
 that represents the number of feet John Rey has walked toward Charlotte since they started walking.

Since \( x \) represents the number of feet that John Rey has traveled toward Charlotte, the expression representing the number of feet John Rey has walked toward Charlotte is simply:

\[
x
\]

This is because \( x \) directly describes John Rey's distance traveled in feet since he started walking.

2. How would the expression change if John Rey walked faster than Charlotte?
3. What equation would describe the total distance between John Rey and Charlotte after walking for a certain time?
4. If they meet after both walking for 110 feet, how long would that take if they walked at a constant speed?
5. How would you express their combined total walking distance?
