### Is unit km per hour per second same as km per second per hour?

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

### A car accelarates uniformly from 36kmhr to 54kmhr in 10s find accelaration and distance traveled by the car during this interval of time?

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

### How do you convert a speed of 73.5 km hr to m sec?

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

### How do you convert 12.7km h into ms?

(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)
