  6. The problem is that you left something out of the problem.

    This doesn't make any sense:

    " is being completed at space of one-length of its length"

  7. A 8-kilometer roadway under construction is being completed at a pace of one-tenth of its length per week. After 5 weeks, how many meters remain to be completed?

  14. That answer tells you how many meters are completed in 5 weeks. Now, subtract that from 8,000 to find how many meters need to be completed.
