A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core esponds that it is too much of an inconvenience to have this busy road obstructed for three months, so the job must be completed in one month. If the relationship between construction time and crew members is inversely proportional, how many crew members does the construction team need if they are to complete the job in one month?

Answer:
The relation between construction time and crew members is inversely proportional. Hence if the time reduces by a factor of 3 from 3 to 1 month, the now of crew members must be 3 times.
Hence no of crew members needed = 9 x 3 = 27 people to complete the job in a month.
So 27 - 9 = 18 additional people must be employed.
