Answer 1

To convert the speed from kilometers per hour to miles per hour using the conversion ratio of 1 kilometer ≈ 0.62 miles, you can use the following formula:

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

Given that the airplane travels about 900 kilometers per hour, we can calculate:

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

Calculating that:

\[ = 900 \times 0.62 = 558 \, \text{miles per hour} \]

So the airplane’s speed in miles per hour is **558**.
