Question

Owners of a recreation area are adding water to a pond. The graph below shows the amount of water in the pond ( in liters) versus the amount of time that water is added (in hours)

Answer 1

Okay I just got so tired and tired lol I’m so sad I woke him crying and

Answer 2

The amount of water in the pond per hour is 300 liters per hour

How to determine the amount of water in the pond per hour?

From the graph, we have the following points:

(x,y) = (0,100) and (1,400)

This means that:

• There are 100 liters of water in the pond at 0 hours
• There are 400 liters of water in the pond at 1 hour

The amount of water per hour is the calculated using:

Rate = (y2 - y1)/(x2 - x1)

Substitute known values

Rate = (400 - 100)/(1 - 0)

Evaluate the quotient

Rate = 300

Hence, the amount of water in the pond per hour is 300 liters per hour
