Question

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 position of the truck compared to the surface of the water?

Answer 1

Answer:

s+1.5=4.8

s = 4.8-1.5=3.3

Answer 2

Answer:

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?

The position of the trout is 3.3 meters below the surface of the water.

Step-by-step explanation:

Given:

Jamal's position from the surface of the water = 1.5 meters

Trout's position with reference to Jamal's position =4.8 meters (Below)

Trout's position from the surface of the water is unknown.

Let

Trouts position be 's'.

And the surface of the water as equivalent to the origin (0,0) co-ordinate of the Cartesian.

Below water we will assign negative height as it lies on negative y-axis (below the origin).

We have to find 's',which can be known from adding both the values.

$s+1.5=4.8$

$s = 4.8-1.5=3.3$

So the trout is swimming 3.3 meters below the surface of the water.

We can say that it is below the water so it can also be written as negative 3.3 (according to our coordinates).

The position of the trout is 3.3 meters below the surface of the water.
