Extremely fast:
1 hour = 3600 seconds
speed = distance/time = 1 mi / 45 s = 1/45 mi/s = 1/45 mi/s x 3600 s/hr = 3600/45 mi/hr = 80 mph!
That is an average speed of 80 mph - faster than the legal speed limit for cars in many countries. And that is when it is crawling! Some ant!
The average speed was 6.433 mph.
An average speed of approx 10.9 mph.
Average speed is about 6 mph.
No, that is terrible. Few people run a mile in more than 6 minutes. 5 minutes 30 seconds is about average. The fastst person ran it in 3minutes 58 seconds
That depends on your speed. If you have speed, you can solve using this: 2640(converted .5 mile to feet) / speed(fps, feet per second) = time(seconds)
A quarter mile in 10.6 seconds = about 85 mph average speed.
A mile in 2 minutes 20 seconds equates to an average speed of 25.7 miles per hour.
The average speed was 6.433 mph.
If your average speed for the whole mile is 4.5 mph, your finishing time will be around 13 minutes 20 seconds.
An average speed of approx 10.9 mph.
The number of seconds in a mile varies according to the speed that you are traveling. For example, if you are going 60 miles per hour, then there are 60 seconds in each mile.
A 4-minute mile means an average speed of 15 miles per hour.
15.4 seconds
Depends on your speed.
Previously Written:: "WRONG!the average speed is the mean..or (1000 + 1) divided by 21000 miles an hour"Edited Answer::You have to take in to account of not only the speed but the distance traveled in the time allotted. You cover two miles in 3603.6 Seconds or roughly one mile per 1,801.8 Seconds which translates into 30.03 Minutes.2 Miles in 60.06 Minutes translates to traveling a little bit slower than 2 miles per hour.The only way to get the average speed or the mean is if you traveled at 1000 MPH for an hour, then traveled another hour at 1 MPH. You would have traveled 1001 Miles which then you could divide that by how many hours you drove. Then your average speed would be 500.5 MPH.It's a trick question, because you only travel one mile for 1000 MPH. Which makes the mile traveled in 3.6 Seconds. Hardly enough for an average speed of anything more than 2 Miles per hour.
This is an average speed of 4.3 miles per hour.
Seconds is a unit of time, mile is a unit of length; you can't convert one to the other. To solve speed problems, use the formula distance = speed x time. Solving for time: time = distance / speed.
