Answer:
1.5 times per second
(1 time per second if rounded to a whole number)
Step-by-step explanation:
1 minuet is equal to 60 seconds
Because you are given 88 vibrations in one minute, you will divide 88 by 60 seconds. You want your answer in seconds.
88/60 gives us 1.466666667 on a calculator
So the guitar gives a vibration of 1.466666667 per second
If we round this, we get 1.5 vibrations per second
Or, if we round 1.4666 to a whole number then it is 1 vibration per second
