Explanation Consider measurements in the west direction as positive and in the east direction as negative. Consider a passenger travelling on a luxury train which is moving west at the speed of 80mph Therefore, V T G = 80 The passenger starts running east at the speed of 10mph. V P T = − 10 Now, the passenger has flipped a dinner roll in the West direction at 25 mph. V R P = 25 Now, the weevil jumps in the east off the roll at 5mph. thus, V W R = − 5 Finally, a roll weevil flea jumps west off the roll weevil at 15 mph. Thus, V F W = 15 Now, the relative velocity of the roll weevil flea relative to roll is calculated as follows: V F R = V F W + V W R V F R = 15 − 5 V F R = 10 mph Now, the relative velocity of the roll weevil flea relative to passenger is calculated as follows: V F P = V F W + V W R + V R
