"Mean" means "average"
= (distance covered) divided by (time to cover the distance)
= ( 90 / 4.5 ) = 20 feet per second

If you ran 100 feet in 10 seconds what was your speed?
100 feet in 10 seconds gives an average speed of 10 feet per second.
What is the speed of a fall of 80 feet in 2.5 seconds?
average speed = (distance) / (time to cover the distance) = (80/2.5) = 32 ft/sec.We know that the speed was not constant during the 2.5 seconds. But with the information given,32 ft/sec average is the only thing we can calculate.
What is the speed if the distance is 40 feet and the time is 0.5 seconds?
40 feet in 0.5 seconds = 80 feet in 1 sec ie 80 fps
A track runner ran 315 feet in nine seconds what was his average speed in feet per second?
315 feet in 9 seconds = about 35 feet per second.
If a thunderstorm is 10 kilometers away How long does it take for the sound to reach you after you see the lightning?
Just under 30 seconds. The speed of sound in air is 1100 feet per second. To cover 10K (which is 6.2 miles), you could multiply 6.2 by 5,280 (the number of feet in a mile), which gives you 32,736 ft. Then divide the number of feet by the speed of sound, and you get 29.76 seconds. Roughly converted the speed of sound is 330 meters per second so it takes 3 second per kilometer, so 30 seconds
How do you determine feet per second?
To determine feet per second, divide the distance in feet by the time in seconds it takes to cover that distance. The formula for calculating speed is Speed = Distance / Time. For example, if an object travels 60 feet in 10 seconds, the speed would be 60 feet / 10 seconds = 6 feet per second.
How long does it take to swim .5 mile?
That depends on your speed. If you have speed, you can solve using this: 2640(converted .5 mile to feet) / speed(fps, feet per second) = time(seconds)
How many seconds to cover a mile at 550 mph?
It would take approximately 3.6 seconds to cover a mile at a speed of 550 mph. This can be calculated by dividing the distance (1 mile) by the speed (550 mph) and converting the result to seconds.
If you ran 100 feet in 10 seconds what was your speed?
100 feet in 10 seconds gives an average speed of 10 feet per second.

How long will it take a car being driven at a speed of 60 miles per hour to travel 13200 feet?
It will take 2 minutes 30 seconds to cover 13,200 feet at 60mph
What is the average speed of 384 feet in 4 minutes 16 seconds?
The average speed is 1.023 miles per hour.
How do i convert 2.97 seconds into feet?
To convert seconds to feet, you need to know the speed or distance being traveled. Without that information, you cannot directly convert seconds to feet.
How many seconds in 25ft?
This is not a valid conversion as seconds measure time and feet measure distance. To convert feet to seconds, you would need information about speed or velocity.
If an object moved 33 feet in 5 seconds what is its speed?
The speed of the object is 6.6 feet per second, calculated by dividing the distance traveled (33 feet) by the time taken (5 seconds).
What is the speed if the distance is 40 feet and the time is 0.5 seconds?
40 feet in 0.5 seconds = 80 feet in 1 sec ie 80 fps
A track runner ran 315 feet in nine seconds what was his average speed in feet per second?
315 feet in 9 seconds = about 35 feet per second.
