Ocean waves of wavelength 100 m have a speed of 6.20 m/s; ocean waves of wavelength 20.0 m have a speed of 2.80 m/s. Suppose that a sudden storm at sea generates waves of all wavelengths. The long wavelength waves travel fastest and reach the coast first. A fisherman standing on the coast first notices the arrival of 100 m waves; 10.0 hours later he notices the arrival of 20.0 m waves. How far is the storm from the coast?
