Blythe and Geoff compete in a 1.00-km race. Blythe's strategy is to run the first 600 m of the race at a constant speed of 4.00 m/s, and then accelerate to her maximum speed of 7.10 m/s, which takes her 1.00 min, and then finish the race at that speed. Geoff decides to accelerate to his maximum speed of 8.10 m/s at the start of the race and to maintain that speed throughout the rest of the race. It takes Geoff 3.00 min to reach his maximum speed. Assume all accelerations are constant. Calculate the time of Blythe's run. (Express your answer to three significant figures.) Calculate the time of Geoff s run. (Express your answer to three significant figures.)
