The solutions of the inequality is 7.99<x<8.01. I think this solutions means the radius of hole in the bolt or something along that, but I'm not sure.
Yes, because if you divide 4 and 3 by 2, you get 2 and 1.5
The inequality statement shows that both Jose and Sue landed on red or blue squares and hence both lost some points. The points they lost were more than the points they gained, which resulted in an overall score having a negative value for each player.
Jose had a final score of -2 and Sue had a final score of -5. This means, Sue scored less and probably lost more points as compared to Jose. There is a difference of 3 points between the scores of both players.
Answer:
Part 1 .
As per the given statement: In t hours the train has traveled s miles.
Distance of the train = s mile
Time = t hours
Formula for :
Speed of the train(v) = 
or
mph .....[1]
Substitute the value of t = 3 hours and s = 180 miles in [1], to solve for v;

Therefore, the speed of the train(v) is, 60 mph
Part 2.
Similarly,
The formula for speed of the train (v) is given by;

Substitute the value of t = 2.5 hours and s = 225 miles to solve for v;

Therefore, the speed of the train(v) is, 90 mph
