S = vt; where S is distance traveled in t time at v velocity. Here v = 3.26 X 10^6 m/sec and period (time to travel one wavelength) = t = 1.25 X 10^-2 sec. Since you are using the period, S will by definition be the wavelength. Just plug in the numbers, you can do the math.

Dimensional analysis makes it easy. If you have a velocity in meters/second, and a time in seconds, a multiplication will give you a length and that is what you do here.
