A bus leaves a station at 1 p.m., traveling west at an average rate of 44 mi/h. One hour later a second bus leaves the same station, traveling east at a rate of 48 mi/h. At what time will the two buses be 274 mi apart.

I have no clue how to set this up to begin figuring out the answer. All help will be greatly appreciated.

Q-Suppose that P and Q are statements for which P →Q is true and for which ┓Q is ture. What conclusion if any can be made about the truth value of each of the following statements?


1-P
2-P^Q
3-PVQ


I am not looking for the right answers; I already have the right answer. What I am looking for is how to start to solve this problem. What am I suppose to do first to solve this.

The correct answers are:

1 – P and Q are False
2- P^Q is false
3- P V Q is false


WHAT I DID:

I think I don’t understand the questions correctly. The thing I did first was that I made the rows for P, Q, ┓Q, P→Q. I know the truth table for P is always T, T, F, F and for Q it is T, F, T, F. For ┓Q we take opposite of Q, which is F, T, F, T Right? And for P→Q we look at the Conditional truth table, which says False only when P is true, and Q is false. So that means that except for the second column, everything else is T. Am I doing it wrong? Isn’t this how we are suppose to do this? I
