Russell and Jane are 220 feet apart when they start walking toward one another. They are walking at the same speed, so whenever Russell travels some number of feet, Jane travels the same number of feet. Let x represent the number of feet Russell has traveled since he started walking toward Jane. a. Write an expression in terms of x that represents the number of feet Russell has walked toward Jane since they started walking. 220-2x Preview b. Write an expression in terms of x that represents the number of feet Jane has walked toward Russell since they started walking. Preview c. Write an expression in terms of x that represents the total number of feet Russell and Jane have walked toward one another since they started walking. Preview d. Write an expression in terms of x that represents the distance (in feet) between Russell and Jane. Preview
