What is the speed of someone running 40 yards in 4 seconds?
Their speed is ten yards per second.Takamo added: There are several variables with in this question. We have to determine how fast a person can cover 40 yards. In this case, it's 4 seconds. To determine the actual speed, as in Miles Per Hour, (MPH) we have to use a known constant. Say, a car going 60 MPH. We all know that a car going 60 MPH is traveling at one mile per minute. There are 60 seconds in a minute, and 5280 feet in a mile, so by dividing the 5280 feetby 60 seconds, we find that the car is traveling at a velocity of 88 FPS(feet per second).A human can run, in this case, 40 yards in 4 seconds. There is 120 feet in 40 yards, so the runner moves at a velocity of 30 FPS. To match the un-known, (the MPH of the runner) and compare it to a known MPH, (the car) we divide the FPS of the car by the FPS of the runner and we get 2.6. This is the variable between them, in that the same distance, the car is traveling 2.6 times faster than the runner. Knowing the speed of the car, 60 MPH, and knowing now, how much faster its going than the runner, we simply divide the MPH of the car, 60MPH by 2.6 and we get the runner's land speed of of 23.07 MPH.
How long does it take to free fall 1200 feet?
After 5 seconds your speed is about 160 feet per second due to gravity speed = gt = 32 x 5 = 160 You travel a distance in 5 seconds of 1/2gt^2 = 400 feet After that it depends on weight but due to air resistance speed is constant near 160 feet per second so to go next 800 feet takes about 5 seconds Total time = 10 seconds to free fall 1200 feet If there were no air, it would take take only about 8.5 seconds
How far can the average person walk in 15 seconds?
If you walk quickly but do not run you can average 6 feet per second or 15 x 6 = 90 feet in 15 seconds ( home plate to first base)
Lenny rode his bike to school at an average speed of 10 miles per hour what was his speed in feet per minute?
10 miles per hour is 10 times 5280 or 52800 feet per hour or 52800 / 60 or 880 feet per minute.
An airplane flies 22 feet in 2 seconds what is the airplane's speed in miles per hour?
7.5 miles per hour
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 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 average speed of 384 feet in 4 minutes and 16 seconds?
1.5 feet per second.
What is the average speed of 384 feet in 4 minutes 16 seconds?
The average speed is 1.023 miles per hour.
What is the average speed of climbing a tree?
I have two Pin Oaks that I climb. One of them I can reach 50 feet in, and that takes me around 45 seconds. The other Pin Oak has less branches in the way, and I can reach 40 feet in just 19 seconds (my record). Normally it takes around 30 seconds. I'm a free climber, so I don't use ropes. The average vertical speed to reach 50 feet in 45 seconds would be 1.1 feet per second, and the average vertical speed to reach 40 feet in 19 seconds would be 2.1 feet per second.
What is the average speed of a baseball that is thrown 90 feet in 2 seconds?
Idk
How fast is your average speed in miles per hour if you traveled 8133 feet in 80 seconds?
speed = distance / time speed = 8133 / 80 101.66 feet per second.
If The fastest person runs 2964 feet in 22.4 seconds how many miles per hour is that show the work?
5280 ft = 1 mile 1 hr = 3600 seconds speed = distance ÷ time = 2964 ft ÷ 22.4 s ≈ 132.32 ft/s = 132.32 × 3600 ft/h ≈ 476,357 ft/hr = 476,357 ÷ 5280 mph ≈ 90 mph They are a very fast runner. The world record for 800m (approx 2624 ft) is 100.91s which is an average speed of approx 17.7 mph. The world record for 100m (approx 328 ft) is 9.58s which is an average speed of approx 23.4 mph. As distances increase, the average speed will drop as humans cannot sustain the fast pace.
If you drop a rock from a great height about how far will it fall after 3 seconds neglecting air resestance?
The acceleration of gravity is 9.8 meters (32.2 feet) per second2.After 3 seconds, the speed of the falling rock is 29.4 meters (96.6 feet) per second.The rock's average speed during the 3 seconds is 14.7 meters (48.3 feet) per second.The distance it has fallen = (average speed) x (time) = 44.1 meters (144.9 feet).
How do I solve 'the mean speed in feet per seconds' if I can cover 90 feet in 4.5 seconds?
"Mean" means "average"= (distance covered) divided by (time to cover the distance)= ( 90 / 4.5 ) = 20 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.
The runner ran 1500 meters in 5 minutes and 22 seconds what was his speed in minutes and seconds?
First lets know the formula of average speed: average speed= distance/time taken here the distance: 1500 m and time taken: 4 minutes (the metre unit always should be with second unit) So lets convert 4 mins into sec: 4*60= 240sec average speed: 1500/240 = 25/4 = 6.25m/s
