					                   Yes. If you are going 22 Mph, since 11 is half of 22 it will take half the time to get there. And half of an hour is thirty minutes giving you 15 minutes  to spare 
					                
					                
					             
					                   Yes. Just halve the original velocity (22miles/1hrs) which gives you 11miles/.5hrs(30 min).
