Use the conversion ratio 1 kilometer equals about 0.62 miles to soive this problem. A helicopter travels about 290 kilometers per hour. What is the helicopter's speed in miles per hour?
To convert kilometers to miles, we can use the conversion ratio of 1 kilometer equals about 0.62 miles.
The helicopter's speed is given as 290 kilometers per hour. To find the speed in miles per hour, we multiply the given speed by the conversion ratio:
290 kilometers per hour * 0.62 miles per kilometer = 179.8 miles per hour.
Therefore, the helicopter's speed is approximately 179.8 miles per hour.
