1 Mile per Hour = 1.46666666666667 Feet per Second
80 Miles per Hour = 117.33333333333333 Feet per second
70mph is 102.667 feet per second.
422,400 feet per hour.
Using the conversion factor of 1 mph = 1.46 feet per second, 80 mph would be equivalent to: 117 feet per second When we talk about the speed of an object, we generally speak in the term of miles per hour (mph). Since accident sequences usually happen in seconds and feet, rather than hours and miles, it is easier to understand speeds effect on distance in feet per second (fps) than mph. The “magic” number for calculating mph into fps is to multiply mph by 1.466. The derivation of this is easy since there are 5280 feet in a mile and 3600 seconds in an hour. 5280 divided by 3600 equals 1.466. Therefore, a vehicle traveling at a rather mundane sounding 25 mph is actually moving at 36.65 feet per second (25x1.466=36.65). What this means in the real world can be explained as follows. At the point of possible perception of a hazard while traveling at 25 mph, using 3 seconds of perception/reaction time would mean that you would have traveled approximately 110 feet before any responsive action takes place (3x36.65=109.95). Add to this the distance necessary to stop an ATV traveling at 25 mph, which is about 42 feet, and you have traveled a total distance of approximately 152 feet.
it would all depend on your stride. a person's stride of 24 inchs yields 40 steps for 80 feet while a person's stride of 36 inches yields 16.6 steps for 80 feet
Answer: 80 m = 262.467 ' Direct Conversion Formula 80 m* 1 ft 0.3048 m = 262.4671916 ft
25 kilometers per hour is 15.53 miles per hour.
One yard is approximately equal to 3 feet. 20 ft. divided by 3 ft. = 6 remainder 2 ft. 6 2/3 yd.
A train is traveling at 60 mph. If the rate of speed increases 4 mph each hour, how long will it be before the ship is traveling at a rate of 80 mph?
0.52 seconds.
80 mph
80 mph = 7,040 feet per minute.
80 fps = 54.55 mph (rounded)
80 and 2/3 feet per second or 80'8" per second

It takes: 600/80 = 7.5 hours
The equivalent of an 80mph pitch from 47ft at 54ft is 54/47*80 = 91.9 mph.
Two hours.
It takes 45 seconds.
12 mph
