The product of speed and time is distance. To calculate the total distance you multiple the speed in kilometers per second by the time at that speed in seconds, do this for all 3 different speeds then add them up, the 17.4 minutes eating does not affect the answer at all. to convert from minutes to seconds multiply time in minutes by 60, to convert from km/h to km/s divide km/h by 3600.
B is the correct answer y=Asin(wt-kx) A=amplitude f=frequency x=wavelength since refraction is not on the wave formula,then option B is the correct answer
