Question

The value of 2 km/ h is equal to

Answer 1

Answer:

5/9 m/s

Explanation:

It means that the object covers 2 km in an hour,

$\frac{2km}{1hour} = \frac{2(1000)metre}{1(60)(60)second} =\frac{2000}{3600} =\frac{20}{36} =\frac{10}{18} =\frac{5metre}{9second} =\frac{5}{9} m/s\\ =>0.5555m/s$

It means that the object covers 0.5555 metre in one second

Which is its speed

Here's the shortcut trick to

convert km/h in m/s

Multiply by 5/18

convert m/s in km/h

Multiply by 18/5
