Owen is fishing from a dock. He starts with the bait 2 feet below the surface of the water. He reels out the bait 19 feet, then reels it back in 7 feet. What is the final position of the bait relative to the surface of the water? I GOT 10 feet. Is this correct?

Sagot :

2+19-7=21-7=14 the final position is 14 feet.

Length of Bait which is below the surface of Water=2 feet

Total Length of Bait which is Reeled out =19 feet

It means total length of bait which is not inside the water, that is above surface of water

                                =-19 feet +2 feet

                                = -17 feet

Length of bait which is reeled out after reeling in =7 feet

Final position of the bait relative to the surface of the water

                                               = -17 feet+7 feet

                                                = -10 feet, means the length which is hanging out.

So, Length of bait above the surface of water,from the dock

=|-10 feet|

=10 feet

Yes, Correct.
