Answer:

  • 570 mph
  • 610 mph

Step-by-step explanation:

Let x represent the speed of the slower plane. The faster plane's speed is then x+40. The sum of speeds is ...

   x + (x+40) = 1180

  2x = 1140 . . . . subtract 40

  x = 570 . . . . . .divide by 2

  x+40 = 610 . . . . the speed of the faster plane

The two speeds are 570 mph and 610 mph.
