Question 530738: It takes Maria twice as long to complete a certain type of research project as it takes Jude to do the same project. They both worked on a similar type of project and they finished in 1 hour. How long would each of them take to finish this project working alone?
I tried to set it up many ways, like 2x+1x=60 mins but that did not work, then I tried 2/3 + 1/3= 60 but that still came out wrong. I know the correct answer is: Maria 1.5 hours, Jude 3 hours, but I have no idea how to get the equation. Could you please help?
