Question

A scuba diver is 3.8 meters below the surface of the water. He is descending at a rate of 0.5 meters per minute.

Part 1:
Write an algebraic expression to describe the depth of the scuba diver after any number of minutes.




Part 2:

Describe what the variable represents in this situation.

Answer 1

-3.8 - 0.5m <== ur expression

the variable (m) represents number of minutes

Answer 2

`-3.8-0.5x`

Explanation:

A scuba diver is 3.8 meters below the surface of the water.

So, Depth of scuba driver is - 3.8 m

He is descending at a rate of 0.5 meters per minute.

So, Rate = -0.5 m . min

So,Distance traveled in x minutes = -0.05 x

So, The depth after x minutes = -3.8-0.5x

So, an algebraic expression to describe the depth of the scuba diver after any number of minutes is -3.8-0.5x

The variable x represents the no. of minutes .
