Question

Jeff and Jason are diving near a corral reef in the ocean. Jason is swimming along the bottom of the ocean floor 188.82 feet from the boat's anchor which lies directly below the boat at a depth of 172.22 feet. If Jeff is 20 feet directly above Jason, how far is Jeff from the boat? (round to nearest tenth)

Answer 1

242.5 feet

Explanation:

Jeff's depth = 172.22 - 20 = 152.22

c2 = b2 + a2

c2 = 188.822 + 152.222

c = 242.536

Answer 2

Jason is below the sea anchor, which is below the boat.

Add the two depth measurements: 188.82 + 172.22 = 361.04

Jeff is 20 feet above Jason

361.04 - 20 = 341.04

Jeff is ~341 feet from the boat.
