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.
Multiply them back into each other... You would multiply your answer with the number you divided by (the number ouside the table if you used the table... ) and you should get the larger number you divided.
I think 30c+3d would be the correct answer.
After subtracting 3 from 7, and dividing 4 by 2, you should end up with x=2.
