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
