d = distance between the two cities
v₁ = average speed while going from chicago to kansas city = 440 knots
t₁ = time taken to travel distance going from chicago to kansas city 
time taken to travel distance going from chicago to kansas city is given as 
t₁ = d/v₁ 
t₁ = d/440                                        eq-1
v₂ = average speed while going from kansas city to chicago = 110 knots
t₂ = time taken to travel distance going from kansas city to chicago
time taken to travel distance going from kansas city to chicago is given as 
t₂ = d/v₂ 
t₂ = d/110                                                     eq-2
Given that :
t₂ = t₁ + 3
using eq-1  and eq-2
(d/110) = (d/440) + 3
d = 440
 
        
             
        
        
        
Step-by-step explanation:
9x^3+6x^2-3x 
Cannot be simplified because there are no like terms but can be factored as
=3x(3x−1)(x+1)
 
        
             
        
        
        
Hey!
-------------------------------------------------
Solution:
The ratio is FEMALES to MALES.
So its 18/16, 18:16, or 18 to 16.
~Now we need to simplify.
18:16 → 18/2:16/2 → 9:8
*Note* When you have a ratio you need to know which comes first. If you put males to females that incorrect. It has to be correct according to the question.
