The speed of 54 km per hour in meters per second is 15 m/sec. The distance traveled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

The speed formula:

s = d/t

Where:

d is the distance traveled in m
s is the speed in m.s-1
t is the time taken in s

1. Convert a speed of 54 km per hour into meters per second.

Speedometers are used to measure speed in moving vehicles. Odometers are used to calculate the distance traveled. A graph can be used to calculate the speed as well. The distance-time graph aids in comprehending an object’s speed.

First, convert km/hr to m/sec

km/hr = 1000 m/(60 x 60 sec)

= 1000 m/ 3600 sec

= 5/18 m/sec

From the conversion above, we may conclude that km/hr equals 5/18 m/sec.

Therefore, we must multiply the supplied number by to convert km/hr to m/sec.

5/18 m/sec or 0.28 m/sec

Now,

54 km/hr = 54 x 5/18 m/sec

= 15 m/sec

Therefore, we can say that 54 km/hr is 15 m/sec.
