If y is indirectly or inversely proportional to x, with k as the constant of proportionality, then:

y = k

The relation is also written as: y \alpha x ^{-1}

Indirect/Inverse proportion means that as the first set of quantity in the relation increases, the corresponding quantity from the second set decreases.  

1)  As the speed (s) increases, the time (t) to reach a destination decreases.
      s = k/t

2)  As the number of workers (w)to finish a certain job increases, the time (t) (hours, days, etc.) to finish the same job decreases.
      w = k/t
