Here's the rule you need to know
in order to answer this question:
1 full circle ==> 360 degrees .
Got that ?
Now you could set up a proportion:
(30 degrees) / (0.01 second) = (360 degrees) / (time for full period)
Cross-multiply the proportion:
(30°) · (period) = (360°) · (0.01 sec)
Divide each side by (30°) : Period = (360° · 0.01 sec) / (30°)
= (3.6° · sec) / (30°)
= (3.6 / 30) sec
= 0.12 sec .

Another way to look at it:
30° takes 0.01 second
60° takes 0.02 second
90° takes 0.03 second
120° takes 0.04 second
150° takes 0.05 second
180° takes 0.06 second
210° takes 0.07 second
240° takes 0.08 second
270° takes 0.09 second
300° takes 0.10 second
330° takes 0.11 second
360° takes 0.12 second
The distance between two consecutive points in a wave is called the wavelength.
