Bob is driving from Miami to Philadelphia to go see the 8:20pm Eagles/Giants game with his cousin Scott. At the speed he is driving he computes that the trip will take him 1 hour, so he decides to leave home at around 7:20pm. When he tells his departure time to Scott, Scott tells him that at that velocity, he’ll miss the first half, since he’ll arrive not at 8:20pm however at 9:20pm. What’s the velocity at which Bob is driving his car? What’s the distance among the two cities in Bob’s reference frame and in Scott’s reference frame?
