Jamal stands on a dock 1.5 meters above the surface of the water. A trout swims 4.8 meters below Jamal. What is the depth of the trout compared to the surface of the water?

Since the trout is 4.8m below Jamal and it takes 1.5m just to get to the surface of the water, we will subtract the two numbers.

1.5 - 4.8 = - 3.3 The trout is 3.3 meters below the surface.
