    A construction crew must build a road in 10 months or they will be penalized $500,000. It took 10 workers 6 months to build half of the road. How many additional workers must be added to finish the road in the remaining 4 months?

    Calculate unit rate per one worker:
    10 workers * 6 months = 60 months for one worker

    Calculate workers needed:
    60 months / 4 months = 15 workers

    Calculate additional workers needed:
    Additional workers needed = New workers needed - Original workers needed
    Additional workers needed = 15 - 10
    Additional workers needed = 5 additional workers
