Average trip time

W20529 took 291 trips in our data set. How long were the trips on average? We can use the built-in Python functions sum() and len() to make this calculation.

Based on your last coding exercise, the data has been loaded as onebike_durations. Each entry is a number of seconds that the bike was out of the dock.
