Question

Brian and Maggie are 230 feet apart when they start walking toward one another. They are walking at the same speed, so whenever Brian travels some number of feet, Maggie travels the same number of feet. Let

x
represent the number of feet Brian has traveled since he started walking toward Maggie.

QUESTION: Write an expression in terms of x that represents the number of feet Brian has walked toward Maggie since they started walking.

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

Answer 1

1. 2x

2. (230-x)

Explanation:

Step 1 :

• If 'x' represents the feet distance that has been covered since Brian started walking towards Maggie then the expression can be given as,

= 2x

Since the distance is covered by 2 walkers and hence the total distance will be 2x

Step 2 :

• The distance in feet between Maggie and Brian is given to be 230 ft and hence the distance in feet is given by the expression,

= (230-x)

(230 - x) is the distance covered in feet.
