An illustration of the letter 'A' in a speech bubbles


If cells of plant B make half as much glucose as plant A does, then they make a half of 120 molecules every hour. A half of 120 molecules is 60 molecules.

Now, 60 molecules per hour, how much it means per minute? There are 60 minutes in each hour, so one minute is 1/60 of a hour.

During 1/60 of an hour cells of plant B make 60 times less molecules than during a hour, i.e. 60 times less than 60 molecules, which is clearly 1 molecule.

The answer: cells of plant B make 1 molecule of glucose every minute.
