1. The problem statement, all variables and given/known data Car A leaves school when a clock reads 0.0s and travels at 65 km/h. Car B traveling at 90 km/h leaves from a convenience store +10 km away from the school and 15 minutes later than Car A. a.) What is the displacement of each car after 1.5 hrs. b.) The two cars pass a gas station at 115 km from the school. When did each car pass the station? 2. Relevant equations d=vt t=d/v 3. The attempt at a solution I am in a mental block at the moment. I have asked about a problem earlier today on the forums and I been on a roll with the homework ever since. But now I have reached a mental block on the very last problem. I am beginner at physics. Just taught myself the basics today. I've done a few dozen problems that were assigned for homework and had little problem with them. Would someone be as kind as to descriptively explain to me on how to do this problem. I really want to learn on how to do well in physics, so any tips would be greatly appreciated also. Thanks in advance to all those who took the time to read and/or answer this post.
