That depends upon which 11:10 and which 7:00 you mean: 11:10 am to 7:00 pm is 7 hours 50 minutes 11:10 am to 7:00 am (the next day) is 19 hours 50 minutes 11:10 pm to 7:00 am (the next day) is 7 hours 50 minutes 11:00 pm to 7:00 pm (the next day) is 19 hours 50 minutes. (Using 24 hour notation or including am/pm removes this ambiguity.)
