An undersea earthquake triggers a tsunami.
The tsunami wave travels a distance of 180 000 m180\,000\text{ m}180000 m in 15 minutes15\text{ minutes}15 minutes.
Calculate the speed of the wave in m/s\text{m/s}m/s.
Use the equation:
wave speed=distancetime \text{wave speed} = \frac{\text{distance}}{\text{time}} wave speed=timedistance
