Answer:
100 revolts
Step-by-step explanation:
180s = 3min
150/3 is 50,
50 = 1 min
50 * 2 is 100
1/12 because first u find a common denominator of 12 then you get 9/12 + (-8/12) and then since one is negative and one is positive you have to subtract and you get positive 1/12
I believe that the answer is 20. I am not entirely sure though.
