4x = 20 min
7x = y min

x = 20 / 4
x = 5 min

7*5 = 35 min

Answer:

The instructor recommended cardio minutes for 20 minutes of strength are:

35 minutes.

Step-by-step explanation:

You must identify the following proportions within the text:

7 minutes of cardio = 4 minutes of strength
X = 20 minutes of strenght

With the given data, a simple rule of three can be performed as shown below:

X = (20 * 7) / 4
X = 140/4
X = 35

So it can be seen that the answer is 35 minutes, another way to identify it that the force time became 5 times greater than in the first case (20 is five times greater than 4), therefore, it is logical that the cardio minutes have been multiplied proportionally (7 * 5 = 35).
