There is an inverse relationship between the time (t) it takes to do a job and the number (n) of workers (the more workers. the faster the work gets done).

t = k/n Divide both sides by n

t/n = k

If we have two different numbers of workers, then

t₁/n₁ = t₂/n₂ Multiply each side by n₂

t₂ = t₁ × n₁/n₂

t₂ = 22 × 1/4

t₂ = 5.5 h
