Machine A produces 100 parts thrice as fast as Machine B does. Machine B produces 100 parts in 30 minutes. If each machine produces parts at a constant rate, how many parts does Machine A produce in 6 minutes?	Pick one: A) 20 B) 80 C) 40 D) 60 E) 50
Machine B produces 100 part in 30 minutes. Machine A produces 100 parts thrice as fast as B, so Machine A produces 100 parts in  30/3=

<output>10</output>
10 parts/minute.   10 parts X a total of 6 minutes= 60   60
<result>D</result>
Machine A produces 100 parts thrice as fast as Machine B does. Machine B produces 100 parts in 30 minutes. If each machine produces parts at a constant rate, how many parts does Machine A produce in 6 minutes?
