问题
I've got a column of bus stop ID numbers (Column A) and Column B are various timings of which each value is the time a person boards/alights the bus. In order to know how long the bus is stopped, I want to find the difference between the max/min in Column B given a certain value of A.

So the first 7 rows should print 00:00:17, the next 4 is 00:00:04 etc. since they are of the same A value. Is this possible? Feel like its getting close but not quite. Thanks a million. Any help would be greatly appreciated

Use this one:
=MAX(IF(A1:A6=1889,B1:B6))-MIN(IF(A1:A6=1889,B1:B6))
and press CTRL+SHIFT+ENTER to evaluate it.
