cm/sec, yes?
ok, divide by 100 to go from cm to m. then multiply by 3600 to go from sec to hr
( K cm/hr ) x ( 1 meter/100 cm ) x (1 km / 1,000 meters ) x (1 hr / 3,600 sec )= ( K x 1 x 1 x 1 ) / ( 100 x 1,000 x 3,600 ) (cm - m - km - hr) / (hr - cm - m - sec)= K / 360,000,000 km/secTake the number of cm per hour. Divide it by 360 millionto get the number of km per second.
73.5 km/hour = 73500 meters/hour = 73500/3600 meters/sec = 20.4166 meters/sec
( K cm/hr ) x ( 1 meter/100 cm ) x (1 km / 1,000 meters ) x (1 hr / 3,600 sec )= ( K x 1 x 1 x 1 ) / ( 100 x 1,000 x 3,600 ) (cm - m - km - hr) / (hr - cm - m - sec)= K / 360,000,000 km/secTake the number of cm per hour. Divide it by 360 millionto get the number of km per second.
Hr/60 mins/60 sec
(55 km/hr) x (1,000 m/km) / (3,600 sec/hr) = 15.2777 m/s (rounded, repeating)
( K cm/hr ) x ( 1 meter/100 cm ) x (1 km / 1,000 meters ) x (1 hr / 3,600 sec )= ( K x 1 x 1 x 1 ) / ( 100 x 1,000 x 3,600 ) (cm - m - km - hr) / (hr - cm - m - sec)= K / 360,000,000 km/secTake the number of cm per hour. Divide it by 360 millionto get the number of km per second.
73.5 km/hour = 73500 meters/hour = 73500/3600 meters/sec = 20.4166 meters/sec
( K cm/hr ) x ( 1 meter/100 cm ) x (1 km / 1,000 meters ) x (1 hr / 3,600 sec )= ( K x 1 x 1 x 1 ) / ( 100 x 1,000 x 3,600 ) (cm - m - km - hr) / (hr - cm - m - sec)= K / 360,000,000 km/secTake the number of cm per hour. Divide it by 360 millionto get the number of km per second.
Hr/60 mins/60 sec
Divided speed by 4, then add 2I.E 40km is 12m a sec
There are 1000 meters in a kilometer(1000 m) / (1 km). There are 3600 seconds in an hour, so (1 hr) / (3600 s). you can just multiply (1 km / hr)*[(1000 m) / (1 km)]*[(1 hr) / (3600 s)] to get 0.28 m/s.
2310 sec * 1 min/60 sec * 1 hr/60 min is 0.642 hr.
(350 mi/hr) x (1,609.344 meter/mi) / (3,600 sec/hr) = 156.46 meters/sec (rounded)
(55 km/hr) x (1,000 m/km) / (3,600 sec/hr) = 15.2777 m/s (rounded, repeating)
(meters / sec) x (3600 sec / hr) / [(0.3048 meters / ft) x (5280 ft / mi)] 1.438*3600 / (0.3048*5280) = 3.2167144 mi / hr (mph)
(66 km/sec) x (3,600 sec/hr) = 237,600 km/hr
(12.7 km/hr) x (1,000 m/km) x (1 hr / 3600 sec)= (12.7 x 1000 / 3,600) (km - m - hr / hr - km - sec)= 3.5278 m/sec (rounded)
