Matty jogs 9 km/hr. Identify the correct conversion factor setup required to compute Matty's speed in m/s.

Anastaziya [24]

Answer:

2.5 m/s

Step-by-step explanation:

Matty's speed = 9 km/hr

We need to convert 9 km/hr to m/s

We know that,

1 km = 1000 m

1 hour = 3600 seconds

$v=9\times \dfrac{1000\ m}{3600\ s}\\\\=2.5\ m/s$

So, Matty jogs with the speed of 2.5 m/s.
