Complete question :

Scottie is standing next to a lighthouse on the edge of a cliff overlooking the ocean. The cliff is 30 meters above sea level, and the lighthouse has a height of 15 meters. There is a man fishing in a boat directly below Scottie who has hooked a fish that is 10 meters below the surface of the water.

​

​a. Use positive and negative numbers to represent the locations in relation to sea level.

​Scottie =

​Top of the lighthouse =

​The boat =

​The fish =

​b. How far is Scottie from the fish?

meters.

Answer:

Scottie = +30 m

Lighthouse = +45m

Boat = 0

Fish = - 10m

40 m

Step-by-step explanation:

Scottie = 30m ( height of the cliff) since he is standing on it's edge

Top of lighthouse = since, lighthouse is located on top of the cliff ; height of cliff + height of light house = (30 + 15) = 45m

The boat = 0 (on the surface of water) ; this is the sea level surface or point

The fish = - 10 m (10 meters below the water surface).

Distance between scottie and fish :

30 m - ( - 10m)

30m + 10m

= 40 m
