Expression for Distance

Complete the table.

  • From the information in the table, determine whether each plane is flying forward, flying backward, or hovering.
  • Then choose one plane that falls into each of these categories, and write an equation that represents distance traveled. Let t = time in hours.
  • Describe the coefficient of t when a plane is flying forward, flying backward, or hovering.

HANDOUT: Forward, Backward, or Hovering

Hint:

  • Remember: In the expression 3 x , 3 is the coefficient ofx .
  • Think about whether the wind and the plane are going in the same or opposite direction.
  • If you know a plane is flying 500 miles per hour, how do you represent the miles it has flown in t hours?
