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

cody is driving down the road, eastbound, with his dog in the back seat of the car. To an outside observer on the roadside, Cody’s speed is 21.0 meters per second. A blue car is passing them at a relative velocity of 2.5 meters per second. Which of the following statements are accurate about this situation? (Choose all that apply) The blue car’s velocity, to a roadside observer, is 23.5 m/s. The blue car’s velocity, to a roadside observer, is 18.5 m/s. The dog’s velocity, relative to Cody, is 0 m/s. Cody’s velocity, from the blue car’s frame of reference, is −2.5 m/s. Cody is stationary from the blue car’s frame of reference.
