Answer:

Speed = 20 m/s

Explanation:

The speed of a bus is 72 km/h

The SI unit of speed is m/s

We need to convert it into m/s

We know that,

1 km = 1000 m

1 h = 3600 s

It means,

[tex]s=72\ \dfrac{km}{h}\\\\=\dfrac{72\times 1000\ m}{3600\ s}\\\\=20\ m/s[/tex]

So, the speed of the bus is 20 m/s.
