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 in miles per hour?(1 point) Responses 1,240 1,240 899.38 899.38 1,451.6 1,451.6 558

Answer 1

To convert 900 kilometers per hour to miles per hour using the conversion ratio of 1 kilometer equals about 0.62 miles, you can use the following calculation:

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

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

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

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