Machine A will take 28 minutes to produce 2100 fishing lures while machine B will take 42 minutes to produce 2100 fishing lures
Step-by-step explanation:
Fishing lures per minute produced by Machine A = 75
Fishing lures per minute produced by Machine B = 50
How long will it take both machines running to produce 2100 fishing lures?
Solving For Machine A:
75 fishing lures produced by machine A = 1 minute
1 fishing lures produced by machine A = 1/75 minute
2100 fishing lures produced by machine A = 1/75*2100
= 28 minutes.
Solving For Machine B:
50 fishing lures produced by machine A = 1 minute
1 fishing lures produced by machine A = 1/50 minute
2100 fishing lures produced by machine A = 1/50*2100
= 42 minutes.
So, Machine A will take 28 minutes to produce 2100 fishing lures while machine B will take 42 minutes to produce 2100 fishing lures
