Thanks for your advices andy,
 as I wrote in prevoius  comment, I want to know which factor affect time spent travelling for work,leisure and shopping trips and I do not have any data on distance. for exmaple weman are spent less time travelling to work more than men, etc.

 450 respondants have been asked how long your trip takes? trips including work, leisure and shopping.  morever, they were asked to fill their dairy day in a day which they travel. each person  have at least 2 trips per day. going to a destination ( e.g. work) and coming back home are two trips. and each of trip may take from 1 minute to .... there was no sample who spent less than 5 munite for a trip.
by this detail, whould you please lead me which model is better?

Also, I draw a histogram graph as you suggested, but I cannot make distinguesh which model has better fitting.
