An airplane travels from St. Louis Missouri to Portland Oregon in 4.33 hours if the distance traveled is 2742 km what is the airplanes average speed
To find the average speed of the airplane, we need to divide the distance traveled by the time taken.
First, let's convert the distance from kilometers to miles, as the speed is commonly measured in miles per hour.
1 kilometer = 0.621371 miles
Distance in miles = 2742 km * 0.621371 miles/km
Distance in miles = 1703.681 miles
Now we can calculate the average speed:
Average speed = Distance / Time
Average speed = 1703.681 miles / 4.33 hours
Therefore, the airplane's average speed is approximately 393.91 mph (rounded to two decimal places).
