Explanation

Each human lung contains approximately 300 million alveoli, providing a large surface area for gas exchange.

These tiny air sacs help in the efficient exchange of oxygen and carbon dioxide in the lungs.

Explanation

To convert kilometers per hour (km/h) to meters per second (m/s), multiply by 1000/3600:

72 km/h = 72 × (1000/3600)

= 72 × 5/18

= 20 m/s
