The answer is: "
" .
________________________________________________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: "
" .
_____________________________________________________<u>Note</u>: The question asks, "At this rate, what "FRACTION" of the distance...?" ;
→ As such, we leave the answer in the "fraction" form.

Answer:
4.1x + 29
Step-by-step explanation:
2.3x + 14 + 2x + (-0.2x) + 15
= (2.3x + 2x - 0.2x) + (14 + 15)
= 4.1x + 29
