Answer:

The pilot rising at 30o going up at a rate of 400 mph for 1 hour is higher.

Step-by-step explanation:

  • You need to add one more piece of information. You need a time of some sort, so lets take one hour. And that's without any loss of generality. You need 2 triangles.
  • So the triangle on the top represents a plane that has gone 400 miles (in 1 hour)
  • The height off the ground is Sin(30) = h / 400
  • The height off the ground is 400*Sin(30) = h
  • Height = 400 * 0.5 =200 miles off the ground.
  • The bottom triangle shows what happens to a plane travelling upward at a 40 degree angle and going 300 miles
  • Sin(40) = h1/300
  • 300*sin(40) = h1
  • Sin(40) = 0.6437
  • 300*0.6437 = h1
  • h1 = 192.83 miles
  • Answer: the plane going up at 30o is the higher one (by 8 miles about)

Discussion

The pilot rising at 30o going up at a rate of 400 mph for 1 hour is higher.
