Machine A produces 100 parts twice as fast as Machine B does. Machine B produces 100 parts in 60 minutes. If each machine produces parts at a constant rate, how many parts does Machine A produce in 6 minutes?  Choose the correct choice from the following options:	A) 20	B) 30	C) 40	D) 10	E) 16
Machine B produces 100 part in 60 minutes. Machine A produces 100 parts twice as fast as B, so Machine A produces 100 parts in  60/2= 
<gadget id="calculator"> 60/2</gadget>
<output>30</output>
30 minutes.   Now, Machine A produces 100 parts in 30 minutes which is 100/30= 10/3 parts/minute.   10/3 parts X a total of 6 minutes = 20   20
