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 airplane's speed nin miles per hour

Answer 1

To convert the airplane's speed from kilometers per hour to miles per hour, you can use the conversion ratio that 1 kilometer equals about 0.62 miles.

Given:

• Speed in kilometers per hour = 900 km/h

To convert to miles per hour, use the formula:

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

Now plug in the value:

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

Calculating that:

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

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