max rides his scooter toward kim and then passes her at a constant speed. his distance in feet, d, from kim t seconds after he started riding his scooter is given by d = |150 - 9t|. what does the 150 in the equation represent? what does the 9 in the equation represent?

max rides his scooter toward kim and then passes her at a constant speed. his distance in feet, d, from kim t seconds after he started riding his scooter is given by d = |150 - 9t|. what does the 150 in the equation represent? what does the 9 in the equation represent?

Answer

Brief Explanations:

  1. For the number 150: When (t = 0) (at the start, when Max begins riding his scooter), (d=\vert150 - 9\times0\vert=\vert150\vert = 150). So 150 represents the initial distance between Max and Kim in feet.
  2. For the number 9: The formula for distance - rate - time is (d = rt) (in a non - absolute value context for linear motion). In the expression (150-9t), the coefficient of (t) represents the rate of change of distance with respect to time. Since the speed is constant, 9 represents Max's speed in feet per second.

Answer:

  1. The initial distance between Max and Kim in feet.
  2. Max's speed in feet per second.
