Question

How to convert the speed of an object,which is expressed in km per hour,into m per second?

Answer 1

Answer:

directly multiply the given km per hour to 5/18

Explanation:

because 1 hour=3600 seconds and 1 km=1000 meters

hence, 1000/3600=5/18

Answer 2

Step By Step Explanation

To convert the speed from km/h into m/s,

we have to multiply the speed of that object from the fraction $\sf\dfrac{5}{18}$.

Let's take an example:

Suppose the speed of an object is 18km/h and we have to convert it into m/s.So, let's convert it:

$\sf\dfrac{5}{18}\times18 = 5m/s.$

I hope you've understood.

Additional Information

To convert the speed from m/s to km/h. We have to multiply the given speed from the fraction $\sf\dfrac{18}{5}$.
