Question

The Westminster Widget Company has an old machine that can produce 50 widgets in five hours. Now they have purchased a

new machine that can produce 30 widgets in two hours. Working together, how long will it take the two machines to produce
100 widgets?
4 hours
16 hours
hour
8 hours

Answer 1

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

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!
