Problema Solution
A particular amusement park ride will make 156 revolutions in 180 seconds. At this rate, how many revolutions will it make in 2 minutes?
Answer provided by our tutors
t = 2 minutes = 120 seconds
Since the rate is v = 156/180 revolutions per second the number of revolutions in t = 120 seconds is:
v*t = (156/180)*120 = 104 revolutions
In 2 minutes there will be 104 revolutions.
