(C) 30 seconds
(D) 45 seconds

Answer 1

The student should use friction when washing her hands for at least 20 seconds. Rubbing hands together with soap and water for 20 seconds effectively removes pathogens and prevents the spread of diseases.

Step-by-step explanation:

The student should use friction when washing her hands for at least 20 seconds. According to the CDC (Centers for Disease Control and Prevention) recommendations, rubbing the hands together with soap and water for 20 seconds is an effective way to remove pathogens and prevent the spread of diseases.

An easy way to time 20 seconds is by humming the "Happy Birthday" song from beginning to end twice. This ensures that enough time is spent on each hand and all areas, including the thumb, wrist, areas between the fingers, and under the nails, are properly washed.

Friction is important because it helps to dislodge and remove dirt, germs, and microorganisms from the skin. By rubbing the hands together, the friction generated helps to break apart the bond between the dirt and the skin, making it easier to wash away.
