I am doing problem in the "units" section and the question gives 2 significant digits, 22miles per hour. it wants feet per second, and only accepts 5 significant digits! this is annoying, how am I supposed to know if wants 32.267 f/s ? The correct answer with sig digits is 32 isn't it? it should ask for sig digits or ask for a certain amount of digits
