Answer:
The second one is the best choice UWU
Step-by-step explanation:
The best choice overall is the second one because the effects are negative. Also, the first one has one positive effect while one negative effect. 
The best choice overall is the second one... 
The best choice isn't the third or the fourth one because the human impacts on the environment are all positive. 
 
        
                    
             
        
        
        
To find the answer, we can first find the distance each of them have, then divide it by their speed to find the time needed.
Distance Steve need to travel: 300 feet
Distance Paula need to travel: 
300+175(behind steve) = 475 feet
Time needed respectively:
Steve: 300 ÷ 9 = 33.33.. seconds
Paula: 475 ÷ 15 = 31.66... seconds
As we can see from the result, Paula would take less time to reach the goal (31.66<33.33),
therefore, Paula win the bike race by:
33.33-31.67
=1.66...
≈1.67 feet
Thus Paula won by 1.67 feet.
Hope it helps!
