The speed in feet per second is quite similar to the speed in miles per hour, which you can read off your speedometer. There are 5,280 feet per mile, and there are 3,600 seconds per hour. Those are roughly similar numbers.
Sound
Light travels 186,282.397 miles per second. That is 983,571,056 feet per second.
20 feet per second.
At 40 mph, a vehicle travels approximately 58 feet per second. The average reaction time for a driver is about 1.5 seconds, which means the reaction distance would be around 87 feet (1.5 seconds x 58 feet/second). Additionally, the stopping distance will vary depending on road conditions and vehicle braking capabilities. Therefore, at 40 mph, the total stopping distance can be around 120-140 feet when factoring in both reaction and braking distances.
v = s / t v = 1500 / 5 v = 300 feet/second Ans.//
Sound travels at 1,088 fps.
Sound is the closest to that figure. The speed of sound at sea level is ~1,116.44 feet per second.

220 kph = about 200.5 feet per second.
Anything that travels 1,635 miles per hour.
1,100 feet per second = 66,000 feet per minute
Light travels faster than sound. Light travels at a speed of about 186,000 miles per second (300,000 kilometers per second) in a vacuum, while sound travels at a speed of about 1,125 feet per second (343 meters per second) in air.
Light travels 186,282.397 miles per second. That is 983,571,056 feet per second.
20 feet per second.
That's aproximately the distance sound travels in one second, in air. Since light travels at a speed of 300,000 kilometers per second, the answer is, approximately 300,000 kilometers.
Something that travels 100.9 MPH travels 147.99 feet per second. ((100.9 * 5280) / 3600). To travel 60.5 feet would take 0.41 seconds.
Anything that travels 1 mile (5,280 feet) in 2 minutes (120 seconds) is moving at 44 feet per second. 5280/120=44.
