Devise a plan:
Let x the amount of time they will work together.
[tex] \sf{30( \frac{x}{5} + \frac{x}{6} ) = 1(30)}[/tex]
Carry out the plan:
[tex] \sf{5x + 6x = 30} \\ \sf{11x = 30} \: \: \: \: \: \: \: \: \\ \sf{x = \frac{30}{11} } \: \: \: \: \: \: \: \: \: \\ \: \: \: \sf{ \boxed{ \sf{x = 2.7 \: hours}}}[/tex]
