in a marathon race (42.195 km), the winner’s time is 2 hours, 13 minutes, and 9 seconds, while the second-place time is 2 hours, 26 minutes, and 6 seconds . The distance is 2.664 km.
D = distance of marathon = 42.195 km = 42195 m
tw = time taken by winner = 2 h 17 min = 2 (60) + 17 = 137 min = 137 (60) = 8220 sec
Vw = speed of winner
speed of winner is given as
Vw = D /tw = 42195/8220
ts = time taken by second place = 2 h 26 min 14 sec = 2 (60)(60) + (26)(60) + 14 = 8774 s
Vs = speed of second place
speed of second place is given as
Vs = D /ts = 42195/8774
distance of the second place holder from the finish line is given as
D' = Vs (ts - tw)
D' = (42195/8774 )(8774 - 8220)
D' = 2664.24 m
D'= 2.664 km

Answer:

Step-by-step explanation:
Let's find our C value for the quadratic equation.

That is our C. Since we added 9 to one side, we have to do the same to the other. We get:

Now, lets form the left side as a binomial squared.

Let's square both sides now:

Now, we subtract 3 from both sides to isolate the variable, X:

This means that the answers are: 

I do not understand your answers though. Answer A makes no sense, answer B is 221, answer C is 115, and answer D also does not make sense. If you could clarify this portion, maybe I can help you find your alphabetic answer
 
        
             
        
        
        
To do this problem, you gotta cross-multiply. SO, 

 multiplied by 

12 times 14 = 168
21 times 3 = 63
Then the final answer is
