"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 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)
If you ran 100 feet in 10 seconds what was your speed?
