\(\dfrac{1}{t} = \dfrac{1}{a} + \dfrac{1}{b}\)

General Formula for work-person-rate problem
\(\dfrac{W_1}{M_1\cdot H_1}\) = \(\dfrac{W_2}{M_2\cdot H_2}\)
where W is the work to be done
M is number of persons required
H is the time required.
\(\dfrac{W_1}{M_1\cdot H_1}\) = \(\dfrac{W_2}{M_2\cdot H_2}\)
where W is the work to be done
M is number of persons required
H is the time required.
