Answer:
59.65 mph.
Step-by-step explanation:
To convert kilometers per hour (km/h) to miles per hour (mph), we can use the conversion factor: 1 km/h = 0.621371 mph.
Given that the ash from Mount Saint Helens is traveling at approximately 96 km/h, we can calculate its speed in miles per hour:
Speed in mph = Speed in km/h × 0.621371
Speed in mph = 96 km/h × 0.621371
Speed in mph ≈ 59.65 mph
Therefore, the ash from Mount Saint Helens is moving at approximately 59.65 miles per hour.
