The distance to fly direct from Detroit to Los Angeles is about 1,960 miles.The flight takes 4 hours 53 minutes.What is the plane's average speed in feet per second to the nearest foot per second?

1 mi=5280 ft.

4 hr 53 min=17580s
1960 mi=10348800 ft
10348800/17580s = 589 ft/s.

Answer: 589

Thanks.(:

To find the plane's average speed in feet per second, we need to convert the distance from miles to feet and the time from hours and minutes to seconds.

First, let's convert the distance from miles to feet. There are 5,280 feet in a mile, so to convert miles to feet, we multiply the distance by 5,280:

1,960 miles * 5,280 feet/mile = 10,339,200 feet

Next, let's convert the time from hours and minutes to seconds. There are 60 minutes in an hour, so we need to convert the minutes to hours by dividing by 60:

4 hours + 53 minutes/60 minutes/hour = 4.88333 hours

Finally, we need to convert the hours to seconds by multiplying by 60 (as there are 60 seconds in a minute):

4.88333 hours * 60 minutes/hour * 60 seconds/minute = 17,600 seconds

Now, we can calculate the plane's average speed in feet per second by dividing the distance (in feet) by the time (in seconds):

10,339,200 feet / 17,600 seconds ≈ 587 feet/second

Therefore, the plane's average speed is approximately 587 feet per second to the nearest foot per second.
