The required average speed of the flight is 485.25 miles per hour.
Given that,
Key west, Florida to Seattle, Washington is 3,518 miles. If it takes 7 hours and 15 minutes to fly there, what is the average speed is to be determined?
The average of the values is the ratio of the total sum of values to the number of values.
Speed is defined as when an object is subjected to move, the distance covered by the object in a certain time interval is the speed of that object.
Total distance to fly = 3,518 miles
Total time = 7 hours 15 minutes = 7 + 15/60
= 7.25 hour
Speed = distance / time
= 3, 518 / 7.25
= 485.25 miles / hours,
Thus, the required average speed of the flight is 485.25 miles per hour.
