Amelia 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 Amelia who has hooked a fish that is 10 meters below the surface of the water. Use a positive or negative number to represent the location in relation to sea level. Amelia= Top of the Light house= The Boat= The Fish= How many meters is Amelia from the fish?

Respuesta :

55 or 45 meters not sure

Answer:

Amedia =  30 m

Top of the Lighthouse = +45 m

Boat = 0

Fish = - 10 m
The distance between Amelia and the fish  is 40 meter

Step-by-step explanation:

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

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

-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 Amelia  and fish :

30 m - ( - 10 m) = 30 m + 10 m = 40 m
