LearnEnglish Hub
In our new Learning hub, you can put your language into practice. Take part in the activities and practise your English skills by writing comments, recording yourself speaking and sharing photos with descriptions.
Do the preparation task first. Then read the text and do the exercises.

Both forms (an hour and per hour) are correct and are widely used. There is no difference in meaning.
