As cute as this problem is, there is not enough information, since you didn't tell us anything about the town! Nor where the colors were heading nor where they are now.
If all the colors were heading toward town.
rate * time=distance
red
50*(t)=200
t = 4
yellow
40*(t)=30
t=0.75
blue
75*(t-15)=50
t=15.6667
Green
60*(t-15)=25
t=15.4167
white
30*(t-30)=10
t=30.3333
The lowest t's arrive first

------------
For each color use time = distance/rate
The color with the smallest time will get to town first.
