Question

following problem. An airplane travels about 900 kilometers per hour
What is the airplane's speed in miles per hour?

Answer 1

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

Given that the airplane travels at 900 kilometers per hour, you can calculate the speed in miles per hour as follows:

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

Substituting the values:

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

Now, perform the multiplication:

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

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