To convert kilometers to miles, we multiply by the conversion ratio of 0.62.
So, the helicopter's speed in miles per hour can be calculated as:
290 km/h * 0.62 mi/km = 179.8 mi/h
Therefore, the helicopter's speed in miles per hour is 179.8 mph.
Use the conversion ratio 1 kilometer equals about 0.62 miles to solve this problem. A helicopter travels about 290 kilometers per hour. What is the helicopter's speed in miles per hour?
