Robo-Billy can do 10 J of work in 10 seconds. Robo-Susie can do 10 J of work in 5 seconds. Determine the amount of time that Robo-Billy and Robo-Susie combined can do 20 J of work. (You may assume, of course, that Robo-Billy and Robo-Susie physically combined into a super robot that exerts power equal to the sum of the powers of the initial bots.)
