The velocities of commuter trains A and B are as shown. Knowing that the speed of each train is constant and that B reaches the crossing 3 min after A passed through the same crossing, determine the angle of line of action of distance between the fronts of the engines 10 min after A passed through the crossing. Choices: A. 1.4 deg left-up B. 1.5 deg right-up C. 1.7 deg left-down D. 2.0 deg right-down
