# How do you convert 73 mi/h = ____km/s?

Jun 20, 2018

$3.26 \cdot {10}^{-} 2 \setminus \text{km/s}$.

#### Explanation:

Well, we know that

$\text{1 mile = 1.609 km}$

and

$\text{1 hour = 3600 seconds}$

So, we have,

$\text{73 miles/hr" = (73*1.609)/3600 \ "km/s}$

$\setminus = \text{0.0326 km/s}$

$= 3.26 \cdot {10}^{-} 2 \setminus \text{km/s}$
