- Arthur and Betty start walking toward each other when they are 100. m apart. Arthur has a speed of 3.0 m/s and Betty has a speed of 2.0 m/s. Their dog, Spot, starts from Arthur's side at the same time and runs back and forth between them. By the time Arthur and Betty meet, what is Spot's displacement?Two buses start at the same time towards each other from terminals A and B, 8 km apart. The time needed for the first bus to travel from A to B is 8 minutes and of the second bus B to A is 10 minutes. How much time is needed by each bus to meet each other if they traveled at their respective uniform speeds. In what distance from A, in meters, the bus will meet?Two locomotives 70 kilometers apart are travelling on the same track towards each other, Engine A moves at 22 kilometers per hour east and engine B moves at 13 kilometersper hour west. At the instant both trains begin moving, an annoying mutant fly beginsflying from engine A towards engine B at 33 kilometers per hour . The instant it touchesB, it turns around and flies back. It goes on this way until the two locomotives collideand the mutant fly is finally squashed. So, before its untimely demise, a) what is the total distance the fly flew? b) the time it took till it was eliminated and c) the average velocity of the fly? how can i find this please
