1. The problem statement, all variables and given/known data A car travels at a speed of 30 km/h for a distance of 12 km. It then reaches a freeway where it travels at 85 km/h for 40 km. Find the average speed of the car for the entire trip. 2. Relevant equations t=change in x over change in v. 3. The attempt at a solution I know the equations for speed and velocity, but I can't figure out how to apply them to this problem. I made several attempts, which I erased. I don't want anyone to solve the problem for me, but I would really appreciate a list of steps and/or the directions for applying the formula. Thanks in advance!
