A tense is a way of referring to a time (past, present or future) in language. Eg. if you say 'I have walked half a mile today', you are using the past tense because you have finished walking at the moment of speaking. Within each tense, there is a further subdivision: simple and continuous. If you want to stress the duration of the action of which you speak (the fact that it is/was/will be going on), you use the continuous. Here are some examples of every tense and its variations: present simple: I walk present continuous: I am walking present perfect simple: I have walked present perfect continuous: I have been walking past simple: I walked past continuous: I was walking past perfect simple: I had walked past perfect continuous: I had been walking future simple: I will walk future continuous: I will be walking future perfect: I will have walked future perfect continuous: I will have been walking

The answer depends on the walker's stride which has not been specified.
The difference is that "has been" is grammatically correct. "Is been" does not work because "been" refers to the past while "is" refers to the present. "Has been" works because both "has" and "been" agree in tense.

"There was a young man named Rollocks, who worked for Ferrier Pollocks. As he walked on the Strand. With his girl by the hand. The tide came up to his knees." "Now that's prose," he continued. "If the tide had been in, it would have been poetry."
"could" asumes it may have, "would" asumes it was.
"TO" means to go to, to see. "IN" means to take part in, be part of
