Answer 1

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

The calculation is as follows:

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

Substituting the given speed:

\[
\text{Speed in miles per hour} = 900 \, \text{km/h} \times 0.62
\]
\[
\text{Speed in miles per hour} = 558 \, \text{miles per hour}
\]

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