Question

A guitar string vibrates back and forth 88 times in 1 minute. what is its period in seconds?

Answer 1

1.5 times per second

(1 time per second if rounded to a whole number)

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
