Question

Armando and Bianca are 290 feet apart when they start walking toward one another. Bianca walks twice as fast as
Armando so whenever Armando travels x feet, Bianca travels 2x feet. Let (x) represent the number of feet Armando has
traveled since he started walking toward Bianca.

1.) Let (d) represent the distance (in feet) between Armando and Bianca. Write a formula that expresses (d) in terms of (x).

Answer 1

9514 1404 393

Answer:

  d = 290 -3x

Step-by-step explanation:

For each x feet that Armondo travels toward Bianca, Bianca travels 2x feet toward Armondo. The net effect is that the distance between them decreases by x+2x = 3x feet. The distance starts at 290 feet when x=0, so the distance can be described by ...

  d = 290 -3x
