No. The value km/hr is a speed. The value km/sec/hour is acceleration (how many km/sec do you gain each hour).

73.5 km/hour = 73500 meters/hour = 73500/3600 meters/sec = 20.4166 meters/sec

3,750 sec

(1 km/hr) / [ (1.609344 km/mi) x (3,600 sec/hr) ] = 0.0001726 mi/sec (rounded)Multiply [Km/hr] by 0.0001726 to get [mi/sec] .Or divide it by 5,793.6 .

(66 km/sec) x (3,600 sec/hr) = 237,600 km/hr

No. The value km/hr is a speed. The value km/sec/hour is acceleration (how many km/sec do you gain each hour).

about 300,000 km per sec.

Acceleration = (change in speed) / (change in time) = [ (54 - 36) km/hr ] / (10 sec) = (18 km/hr) /(10 sec) = (1.8 km/hr-sec) x (3,600 sec / hr) = (1.8 x 3,600) (km - sec / hr2 - sec) = 6,480 km / hr2 Average speed during the 10 seconds = (36 + 54) / 2 = 90/2 = 45 km/hr Distance = (average speed) x (time) = (45 km/hr) x (10 sec) x (1 hr / 3,600 sec) = (45 x 10 / 3,600) (km - sec - hr / hr - sec) = 0.125 km = 125 meters

After :8 Sec - 161 km/hr60 Sec - 1609 km/hr120Sec - 4828 Km/hr

73.5 km/hour = 73500 meters/hour = 73500/3600 meters/sec = 20.4166 meters/sec

(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)
