the answer to you last Q- is 1 hour. Do your own school work.|||Some of these are so simple, you just need to do your own work. hint distance = rate * time



Hint for question 20, when both cars have gone the same distance they will meet or the one will catch up to the other.



distance = rate * Time, so, you have two equations,



the first card distance = 48 kph * (t+.5) he has been traveling .5 hours longer than the other guy



distance = 63 kph * (t), set them equal to each other



48(t + 0.5) = 63 * (t), solve for t, then plug in to either of the other equations and solve for distance.



Get busy.|||Have you ever thought of asking your math teacher for help?|||only because im bored at work...i decided to give these a try. i couldnt figure out 15-20. but heres 1-14 at least.
