Average speed = Distance/Time = 2.5 miles/15 minutes = 10 miles per hour

To join the army, two miles must be done in 15 minutes and 53 seconds, so average is somewhere around there.

distance = rate * time time= distance / rate Time for first leg = 15 miles / 40 miles/hr = 0.375 hr Time for second leg = 15 miles / 10 miles/hr = 1.5 hr Total time for trip = 1.875 hr rate=distance/time Average rate = (15+15)/1.875 = 30/1.875 = 16mph!

The woman jogs at an average speed of 6.5 miles per hour. The average sprinting speed is up to 15.9 miles per hour or running 100 meters in 14-15 seconds.

im a 15 year old girl in my first year of running, and i can do it in 23 minutes

ten

Running a mile in exactly 4 minutes equates to a speed of 15 MPH.

11/2 miles in 15 minutes = 6 mph

If you average 65 miles per hour for the entire distance your driving time would be about 15 minutes.

Umm.. 948/15 = 63.2 miles/hr

15 to 18 kph

at 13 i was running a 7:04 to 7:15. but now im a freshman and running around a 5:45

6.4mph

the average time should be around 13-15 seconds. the good athlete will run in the 12 range. if you are running under 12 you are fast

Divide Distance by Time to calculate Speed. 15 / 70 = .2142857 miles per minute or an average of 1/5 to 1/4 mile per minute.

If you average 60 miles per hour for the entire distance your driving time would be about 1 hour and 15 minutes.

If you average 65 miles per hour for the entire distance your driving time would be about 11 hours 15 minutes.

= 2.5 / (15/60) miles/hour = 10 miles/hour

An average of 15 mph.

The average speed is(4 x the number of nautical miles the boat traveled in that time) knots.

The distance from Nottingham, UK to Santiago, Chile is 7,276 air miles. The average flight time is between 13 and 15 hours.

The average pace if you run 17 miles in 2 hours 15 minutes is 7.56 mph

Time = Distance/Speed = 300 miles/20 mph = 15 hours.Time = Distance/Speed = 300 miles/20 mph = 15 hours.Time = Distance/Speed = 300 miles/20 mph = 15 hours.Time = Distance/Speed = 300 miles/20 mph = 15 hours.

well I would say about 14 mph because when I was 8 I was running my average at 10 mph when I was 9 I was running my average at 12 mph and now I can run my average at 13 mph my top was really close to 15 mph so that's how I came up with that.

You can also walk or run instead of driving the 15 miles distance.But first you will have to give us the average speed that you are doing it at.Time = distance / speed (use consistent units).
