use the conversion ratio 1 kilometer equals about 0.62 miles to solve the following problem an airplane travels about 900 kilometers per hour what is the airplanes speed in miles per hour

Answer 1

To convert the airplane's speed from kilometers per hour to miles per hour using the conversion ratio of 1 kilometer equals about 0.62 miles, you can multiply the speed in kilometers by the conversion factor.

Here’s the calculation:

\[ \text{Speed in miles per hour} = \text{Speed in kilometers per hour} \times 0.62 \]

\[ \text{Speed in miles per hour} = 900 , \text{km/h} \times 0.62 \]

\[ \text{Speed in miles per hour} = 558 , \text{miles per hour} \]

Thus, the airplane's speed is approximately 558 miles per hour.
