Answer:

If they worked together it would take 4 hours for the machines to produce 100 widgets

Step-by-step explanation:

w = widgets     hr = hour     ph = per hour

Old machine - 50w = 5hr = 10ph

New machine - 30w = 2hr = 15ph

Old machine - 20w = 2hr

New machine - 30w = 2hr

Together  - 50w = 2hr x 2

             Final:  100w = 4hr

     I hope this helped!
