Find 25 seconds in the table. That's between 20 and 30, right? So, find the median between 19 and 28:
19 + 28
---------- = 23.5
2
That is around 24 deep knee squats per 25 seconds. Now, use the same method for 65 seconds:
51 + 58
---------- = 54.5
2
That is around 55 deep knee squats per 65 seconds.
Now, explain the method using words. You might wanna use the words "average" or "mean" to describe that process above.
You can't convert miles into gallons those are two different units of measurement.
The first thing is the slope
y = 1/2 x + b is the new line. Now we must solve for b
2 = 1/2 (-2) + b
2 = -1 + b
3 = b
The new line is
y = 1/2 x +3
The first one shown, 400/2, is showing the point on the graph where she walks 400 ft in 2 minutes. In order to find the next proportion, you just have to look two minutes over which in this case is 800 ft for 4 minutes... written 800 over 4.
