A turtle and a rabbit engage in a footrace over a distance of 4000m. The rabbit runs 0.500 km and then stops for a 1.5 hr nap. Upon awakening, he remembers the race and runs twice as fast. Finishing the course in a total time of 1.75 hr, the rabbit wins the race. (a) Calculate the average speed of the rabbit in SI units. (b) What was his average speed in SI units before he stopped for a nap? Assume no detours or doubling back.
