Question 505220: I really need to know how to solve travel and distance
problems (word problems). I do understand the question,
but I can't get the equation. And especially, I am struggling about
solving how much you didn't travel in the problem.
for example: It takes 305km to drive to location A from your house. You estimate you drove at an average speed of 80KPH. It takes you 4 hours and 10 minutes to get to location A. How many hours were you NOT driving?
I really need help with this.
Thank you

Question 505878: Your mom leaves on a trip to Florida, forgetting her suitcase at home. You know that she normally drives 55 mph. However, you do not discover the suitcase until 1 hour after she has left on her trip. If you follow her on her exact route and travel 65 mph., how long will it take you to catch up with her?
Hint: Let d=distance in miles, let t=time in hours it will take to catch up with her and let t+1= time traveled by your mom at a slower rate of speed.
