Math problem that I don't really understand?

Question

Ok well the directions say: "Preform the given opperation. Give the answer with appropriate unit of measure."

Question:

(2revolutions/sec)x(60seconds/min)

To me I honestly don't understand the revolution thing. Please help =)

Answer 1

the sec. cancel out when you mutiply so its 120 rev./min

Answer 2

(2 rev/sec) x (60 sec/min)=120 (rev/sec)X(sec/min)=120rev/min

Answer 3

the answer is 120 RPM (revolutions per minute)

Answer 4

2 rev/sec  x  60 sec/min  =  120  rev/sec x sec/min

120 is your actual quantity,  but lets forget it for a moment

and work on the terms.  

what you have here for terms is:   rev x sec / sec x min

   ( numerators multiplied  over denomenators multiplied)

If this was a numerical fraction,  the sec would cancel out

and you lwould have  rev / min.  Your answer would be

               120 rev/min.

Answer 5

Ok, so:

theres 2 revolutions in a second, and there are sixty seconds in a minute. So in a minute, how many revolutions would there be?

Answer 6

120 revolutions/minute
