100 XP

Calculate the difference in the Start date of the current row and the End date of the previous row and assign it to rides['Time since'].
Convert rides['Time since'] to seconds to make it easier to work with.
Resample rides to be in monthly buckets according to the Start date.
Divide the average by (60*60) to get the number of hours on average that W20529 waited in the dock before being picked up again.
