1/45 m/s
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!
the ant
-- First of all, an ant sitting 17 cm from the center of a CD remains placidly at rest,as the radius of a CD is only 6 cm.-- His old-fashioned cousin, the country ant, sitting 17 cm from the centerof a vinyl record, travels a total distance of (34 pi) cm in each revolution.If he travels a total of 913 cm in 42 seconds, then his speed per minute is(913 cm / 42 sec) x (60 sec / minute) = 1,304.286 cm/minute (rounded)His angular speed is 1,304.286/(34 pi) = 12.21 Rev Per Minute (rounded)(Country Ant is sitting on the vinyl record that was used for the Saturday night danceat the church that ended about an hour ago. In use, the record turned at 78 RPM.After the dance ended and everyone went home, around 9:30, the Victrola eventuallyran out of gas, as there was no one left to crank it up, and it is now coasting to a stop.In the next 42 seconds, he will travel somewhat less than 913 cm. He is experiencinga definite case of αλφα ... angular deceleration ... and will wake up feeling quite unwellin the morning.)
The answer to this riddle is: "A buoyant girl ant". umadbro[
i don't care? -_-
4 meters in 3 minutes so 40 meters per hour
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!
A tyrant

no.
The slope of the ant's displacement vs. time graph The total displacement divided by the time.
1 minute and 43 seconds on average.
The slope of the ant's displacement vs. time graph The total displacement divided by the time.
Its speed was 15cm per second. ( 75cm divided by 5 seconds = distance per each second, which is essentially an expression of speed).
assume the ant is moving at a constant speed. Then in 60 s, the ant moves (29.4 mm / 72.8 s) * 60 s = 24.23 mm.
The slope of the ant's displacement vs. time graph The total displacement divided by the time.
the red ant. they can kill another ant in 10 seconds.
