Oh ok so square root of 2 is irrational since it goes on and on. square root of 18 is an irrational number too 
        
             
        
        
        
Answer:
Difference between the distances traveled by Mary and Kate = 226 feet
Step-by-step explanation:
By applying Pythagoras theorem in right ΔDEF,
(DE)² + (EF)² = (DF)²
By substituting DE = 264 feet and EF = 900 feet
(264)² + (900)² = (DF)²
DF = √(69696+810000)
      = √879696
      = 937.92
Distance traveled by Kate diagonally = 938 feet
Distance traveled by Mary = DE + EF 
                                             = 264 + 900
                                             = 1164 feet
Difference between the distances traveled by Mary and Kate = DF - (DE + EF)
= 1164 - 937.92
= 226.07
≈ 226 feet 
 
        
             
        
        
        
answer: 9
the answer is 9 because 6 ÷ 2 = 3, and if you multiply 3 with 3, you get 9. you multiply the number 3 because you need to find out the distance in miles, and since in inches it is 3, you need to multiply by 3 because that is the formula to get miles.
