Start from the last plane.
Rachel's plane flew 20 ft.
Darren's plane flew twice as far as Rachel's,
so Darren's plane flew 2 * 20 ft = 40 ft.
Amanda's plane flew 19 ft farther than Darren's,
so Amanda's plane flew 40 ft + 19 ft = 59 ft.

Answer:

59 ft

Step-by-step explanation:

Given;

  • Amanda plane flew 19 ft farther than Darren plane
  • Darren plane flew twice as far ad Rachel plane
  • Rachel plane 20 ft

Then Darren's plane must have flown (2 × 20ft) = 40 ft

Amanda's plane would have flown (40ft + 19ft) = 59 ft

Amanda's plane flew 59 ft far.
