It is an average speed of 10 metres per second or 22.4 miles per hour.
sharon sprinter changes her speed from 4.5m/s to 7.5m/s in the middle 1.5 seconds of a 100m race. what is her average velocity for this time period?
There are 60 seconds in one minute. Therefore, 125 seconds is equal to 125/60 = 2.083 recurring (that is, 2.0833333...) minutes or 2 minutes 5 seconds.
Pythagoras! If AB = 100m and BC = 75cm then AC = sqrt (10000 + 5625) = 125
125 what? Seconds? Hours? Days, Millennia? Or is it degrees?
Three seconds on the 100m dash!
9.70 - 9.80 seconds.
The total distance covered by the bird is 450m (150m + 200m + 100m) and the total time taken is 25 seconds (10 seconds + 10 seconds + 5 seconds). Therefore, the average speed of the bird is 18 m/s (450m / 25s).
9.58 seconds for the 100m 19.19 seconds 200m and 4x100m 36.84 seconds
I do 14:89 but 15 or 16 seconds is also good

Approx. 50 seconds
Here's some quick math... Might be wrong: 9.69 seconds is the record in a 100M race 328.08 feet = 100 M 33.86ft/sec for 100M converted to mph... 23.08mph average speed.
boys 100m: under 11.8 boys 200m: under 24.5 seconds girls 100m: under 13 sec girls 200m under 27 sec. These are not outstanding times but are average to above average
