CPM Homework Help : INT1 Problem 11-76

Susan can paint her living room in $2$ hours. Her friend, Jaime, estimates it would take him $3$ hours to paint the same room. If they work together, how long will it take them to paint Susan’s living room?

Hint:

$\frac{1}{2}+\frac{1}{3}=\frac{1}{t}\text{ where }t\text{ represents the time to paint the room together.}$

Now solve for t using a fraction buster. Review the Math Notes box in section 3.3.2
