A long distance runner is in training for a 10 km race and is gradually getting closer to his target speed. His recent times over 10 km have consistently decreased each week. His times for the last five weeks have been 58m 20s, 56m 40 s, 55m 00 s, 53m 20 s and 51m 40 s. It is assumed that his improvement will continue at the same rate. With two more weeks of training remaining, how fast will he be likely to run in the actual race

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
