Question

choose the correct answer. speed of plane a = 450 mph. speed of plane b = 350 mph. both planes leave from kansas city at the same time. plane 1 flies due west. plane b flies due south. after 2.5 hours how far is plane a from plane b

Answer 1

Answer:

1425.22 m

Step-by-step explanation:

dist by a in 2.5 hrs = 1125 m

dist by b in 2.5 hrs = 875 m

We can say that plane a is at (-1125,0)

                    and plane b is at (0,-875)

dist = √((-1125)²+(-875)²) = 1425.22 m
