Total distance = 100 km + 200 km = 300 km
Total time = 2 hrs (first part) + 1/2 hr (stop) + 4 hrs (second part) = 6.5 hrs
Average speed = 300 / 6.5 = 46.154 km/hr (rounded)

The basic relationship between the frequency of a wave and its period is

where f is the frequency and T the period of vibration.
In our problem, the frequency is

so, by re-arranging the previous formula, we can find the period of the wave:
