Answer:the average speed of the flight is 142.1 miles per hour
Step-by-step explanation:
Total number of miles that the woman travelled is 2439.1
The total time that she spent on the flight is 17 hours 10 minutes. There are 60 minutes in one hour. Converting 17 hours 10 minutes to hours, it becomes
17 + 10/60 = 17 + 0.167 = 17.167 hours
Average speed = total distance/total time
Therefore, the average speed of her flight in miles per hour would be
2439.1/17.167 = 142.1 miles per hour
