Answer: 2.244 seconds
Explanation:
The x coordinate of the left peak point is x = 1.870, and its neighboring peak point has an x coordinate of x = 4.114
The difference is 4.114 - 1.870 = 2.244
The period is 2.244 seconds, which is the time it takes to go from one peak to another adjacent. This is the same as going from one valley point to a neighboring valley point.
