3,600
Most hours have 3600 seconds - since an hour has 60 minutes and a minute usually has 60 seconds.
To calculate acceleration in miles per hour per second, first convert the acceleration from 0 to 60 mph in 3 seconds to miles per hour. 60 mph / 3 sec = 20 mph/sec. So, the acceleration in miles per hour per second is 20 mph/sec.
Speed of sound in iron = 5120 metres / sec = 11453 miles / hour
The unit of frequency is always 'reciprocal time' ... "per second", "per minute", "per hour", etc.,no matter what the speed or wavelength may be.Examples:Speed = 10 meters per second, wavelength = 2 meters.Frequency = (speed) / (wavelength) = (10 meters / sec) / (2 meters) = 5 per second.Speed = 100 yards per hour, wavelength = 1 mileFrequency = (speed/wavelength) = (100 yd/hour) / (1 mile) =(100 yd/hour-mile)x(1 mile/1760 yd) = (100/1760) per hour.Speed = 60 ft/sec, wavelength = 1 inchFrequency = (speed/wavelength) = (60 ft/1 inch-sec) x (12 inch/ft) = 720 per sec.
There are 3,600,000 milliseconds in one hour.
1 hour/40 secs = 3600 sec/40 sec = 90 of them.
100 sec = 0.02777... hour (rounded) 1 hour = 3,600 seconds
60s * 60m= 3,600s. 3,600 seconds in a hour.
about 720. or 1100ft/sec
0.0011666666666666666667% how to find out 4,2/(60*60)=answer 60*60 = to find how many sec in a hour 60 min in a hour and 60 sec in a min
1 hour = 60 x 60 = 3600 sec 48 hours = 48 x 3600 = 172800 sec
1 hour = 3,600 seconds
60 multiplyed by 60 is.... WHAT???
(200 ft/sec) x (1mile / 5280 ft) x (3600 sec / hour) = (200 x 3,600 / 5,280) (ft - mile - sec / sec - ft - hour)= 136.364 miles per hour (rounded)
No. The value km/hr is a speed. The value km/sec/hour is acceleration (how many km/sec do you gain each hour).
2 hour = 3600 sec 5 min = 300 sec total sec in 2hr&5min= 3900
1 hour = 3600 seconds.
