Answer:2.6 h
Explanation:
Given
Total Trip distance=450 miles
Meeting starts after 10.8 hours 
safe Fastest speed is  55 mi/h
so if he drives all the to the meeting with max speed then it takes 
and total allowable time is 10.8 
Therefore longest time he can spend over dinner is 
 
        
             
        
        
        
A vertical polarizing filter is used on the lens of a camera,  they block out the light that is horizontally polarized, so they allow all of the vertically polarized<span> light to pass through.</span>
        
             
        
        
        
Answer:
The  velocity  is 
Explanation:
From the question we are told that 
    The initial speed is  
    The  cross -sectional area of the first pipe is  
    The  cross -sectional area of the second pipe is 
Generally from continuity equation we have that 
      
So  
      
=>   
=>
