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?

Answer 1

To convert kilometers to miles, we need to multiply the number of kilometers by the conversion ratio.

Therefore, the helicopter's speed in miles per hour would be:

290 kilometers/hour * 0.62 miles/kilometer = 179.8 miles/hour

Therefore, the helicopter's speed is approximately 179.8 miles per hour.
