The answer is:  " \frac{7}{2} " .
________________________________________________
Explanation:
________________________________________________

(1/6)  / (3/7 hr) =  x/ 1 hr ;

 → (1/6) / (3/7) = x ; 

↔  (1/6) / (3/7)  = x ; 

→  (1/6) * (7/3) = x ; 

The "3" cancels to a "1", and<span /> the "6" cancels to a "2" ; 
  
          →  { since:  " 6 ÷ 3 = 2" ; and since:  " 3 ÷ 3 = 1 "} ;
_____________________________________________________
→  And we can rewrite as:

→  (1/2) * (7/1) = (1 * 7) / (2 * 1)  = 7/2 ; 
_____________________________________________________
The answer is:  " \frac{7}{2} " .
_____________________________________________________
<u>Note</u>:  The question asks, "At this rate, what "FRACTION" of the distance...?" ; 

→  As such, we leave the answer in the "fraction" form.

Expand the polynomial: (6x^2−11y^3)(−6x^2−11y^3)
a_sh-v [17]

on expanding polynomial (6x^2−11y^3)(−6x^2−11y^3) or (6x^2-11y^3)(-6x^2-11y^3) is 121y^6 -36x^4 .

<u>Step-by-step explanation:</u>

We have , (6x^2−11y^3)(−6x^2−11y^3):

(6x^2-11y^3)(-6x^2-11y^3)

⇒ (6x^2-11y^3)(-6x^2-11y^3)

We know that :

(a +b)(c+d) = (ac+ad+ad+bd)

⇒ (6x^2(-6x^2)  - 11y^3(-6x^2) )+(6x^2(-11y^3) + (-11y^3)(-11y^3))

⇒ (-36x^4+66x^2y^3 -66x^2y^3  + 121y^6)

⇒ (-36x^4+ 121y^6)

⇒ 121y^6 -36x^4

Therefore, on expanding polynomial (6x^2−11y^3)(−6x^2−11y^3) or (6x^2-11y^3)(-6x^2-11y^3) is 121y^6 -36x^4 .
