Speed is distance travelled in a given time, so speed = distance / time.
40mph = 40 miles / 1 hour
each mile has 1760 yards, each of 3 feet, so there are 3x1760 = 5280ft in each mile, so 40 miles = 40x5280ft.
Each hour has 60 minutes and each minutes has 60 seconds, so 1 hour = 60x60 = 3600 seconds
So 40mph = 40miles/1hour = 40x5280ft/3600secs = 58.67fts-1
15 mph = 22 feet per second
146.6 feet per second.
14.66 feet per second.
3,000 feet per second = 2,045.45 mph
44 feet per second = 30 mph
At 1000 mph, there are approximately 1467 feet per second.
2,200 feet per second is 1,500 mph
55 mph = 80.6666 feet per second
350 feet per second = 238.64 mph
15 mph = 22 feet per second
40 mph = about 58.6 feet per second.
69 mph is 101.2 feet per second.
To convert mph to feet per second, you can use the conversion factor of 1 mph = 1.46667 feet per second. Therefore, 74.0625 mph is equivalent to about 108.67917 feet per second.
125 mph = 183.33 feet per second.
132 feet per second at 90 mph.
1.46 feet per second at 1 mph.
(19 (mph) * 1760 * 3) / 3600 = 27.86 feet per second (approx) > mph>yards per hour>feet per hour>feet per second
