Stephanie, Regine, and Brian ran a 20 mile race. Stephanie and Regine's combined times exceeded Brian's time by exactly 2 hours. If nobody ran faster than 8 miles per hour, who could have won the race?
I. Regine
II. Stephanie
III. Brian Choose the correct option:	A) I only	B) II only	C) III only	D) I or II only	E) II, or III
Given that S+R=B+2, where S, R, and B are times in which Stephanie, Regine, and Brian completed the race.   Min time one could complete the race is  20/8=

<output>5/2 = around 2.5</output>
2.5 hours. Let's see if Brian could have won the race: if he ran at the fastest rate, he would complete the race in 2.5 hours, so combined time needed for Stephanie and Regine would be S+R=B+2=4.5 hours, which is not possible as sum of two must be more than or equal the twice the least time: 2*2.5= 
<gadget id="calculator">2*2.5</gadget>
<output>5</output>
5. So Brian could not have won the race.   There is no reason to distinguish Stephanie and Regine so if one could have won the race, another also could. So both could have won the race.   Answer: II, or III.
