Question

If an airplane passes directly over your head at an altitude of 3 miles, how far is the airplane from your position after it has flown 4 miles farther at the same altitude?

Answer 1

You'll end up with a right triangle so you can use the Pythagorean Theorem to find out how far away it is from you:

 

c² = a²+b²

 

c²= 3² + 4²

 

c² = 9 + 16

 

c² = 25

 

Now you can solve for c to find out how far away it is.
