If a train arrived at 7:24pm and the trip lasted 8 hours and 46 minutes when did the train leave?

If the train arrived at 7:42, take 46 minutes and add that to 42 which is 70min, take 9 hours and 10min and add it to 7:24 leaving it to be 4:10am

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
