I work that out as 4.87 seconds.
4,000 feet
Impossible to answer ! Feet is a measurement of distance - seconds is a measurement of time (or angles)
40 feet in 0.5 seconds = 80 feet in 1 sec ie 80 fps
"Mean" means "average"= (distance covered) divided by (time to cover the distance)= ( 90 / 4.5 ) = 20 feet per second
1531.2
5 miles/hour (5280 feet/1 mile)(1 hour/3600 seconds) = 7.3 feet per second ================
4,000 feet
You cannot; feet are a measure of DISTANCE while seconds are a measure of TIME.

In 2 seconds at 30 mph (44 ft/s), the distance travelled would be 88 feet. This is calculated by multiplying the speed in feet per second (44 ft/s) by the time in seconds (2 seconds).
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.
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.
40 feet in 0.5 seconds = 80 feet in 1 sec ie 80 fps
"Mean" means "average"= (distance covered) divided by (time to cover the distance)= ( 90 / 4.5 ) = 20 feet per second
87 miles per hour = 1,531.2 feet per 12 seconds
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).
You can't convert distance into time.
