Question

Machine M, working alone at its constant rate, produces x widgets every 4 minutes. Machine N, working alone at its constant rate, produces y widgets every 5 minutes. If machines M and N work simultaneously at their respective constant rates for 20 minutes, does machine M produce more widgets than machine N at that time?

Answer 1

Yes

Step-by-step explanation:

In 4 minutes, machine M produces x widgets

In 20 minutes, machine M produces 5x widgets

Assuming x = 1, in 20 minutes machine M produces 5 widgets

In 5 minutes, machine N produces y widgets

In 20 minutes, machine N produces 4y widgets

Assuming y = 1, in 20 minutes machine N produces 4 widgets

Machine M produces 1 more widget than machine N in 20 minutes assuming x=1 and y=1
