The graphed area is below the line with negative slope and above the line with positive slope. The lines themselves are not shaded, indicating that the sections on the line are not in the solution area, so the third set of inequalities is the correct one.
First, take two points from the graph. Call these points (a, b) and (c, d).
Next, find the slope. You can find this by doing (b-d)/(a-c).
Call the slope m. You will need this later.
Make an equation in slope intercept form (y = mx + b).
Now, take one of the points, and plug it into the equation.
mx + b has the same m as the slope.
From here, you can figure out b (the y-intercept).
To make a system, you do the same thing, but find where it is greater and lower.
This is simple conversion.
Start from getting the numbers of hours.
12 weeks × 5 days × 45 minutes will get the number of minutes spent total (2700mins). Divide this by 60 min to get the number of hours spent total - 45 Hours.
to get the rate - r=laps/time
1800laps/45 hours
rate = 40laps/hour
