Question

If a body moves with a speed v km/h , what will be its speed in m/s​

Answer 1

If the body moves with V km/h then

its speed in m/s = (V*1000)/60*60

= (V*10)/36

= 5v/18

Its speed will be 5v/18 m/s

Answer 2

The speed of a body is defined as the distance covered by the body in a unit of time. It is given by:

                 $Speed = \frac{Distance}{time}$

The commonly used units to denote the speed of the object are Km/h or m/s. The SI unit of the speed is m/s. where m is meter and s is seconds.

Given:

Speed of the body: v km/h

Standard conversions:

1 km = 1000 m

1 hour = 3600 s

Hence, the speed of the body in m/s will be:-

speed,  $S = v \frac{km}{h}$

Equating the value of km and hour in the above equation:

$S = v X \frac{1000}{3600}$

$S = \frac{5}{18} v$

or, 0.28v

Hence, the speed of the body in m/s will be 0.28v or $\frac{5}{18} v$
