Chapter 3, Problem 40 Question Problem Multiply by 0.278 to convert the velocity in km/h to m/s. The two planes are flying head-on. This means they are flying along the same line but in opposite directions. So, the relative velocity is simply the sum of the velocities of the planes. So the pilot of plane A observes plane B approaching at 436.4 m/s. Similarly, the pilot of plane B
