# How do you convert 32.4 meters per second to miles per hour?

72.48 mph

#### Explanation:

32.4 metres per second will be $\times$ 3600 for per hour. ($\times$ 60 each for minutes, then hour)

$\therefore = 32.4 \cdot 60 \cdot 60 = 116 , 640$ m/h

Then to get into km divide by 1000 (I'm going through kilometres because I don't understand miles)

$\frac{116640}{1000}$= 116.64km/h

To convert km in to miles you add half your km to a quarter of that (or multiply original number by 5/8)
Or you use a conversion calculator.

116.64 $\div$2 = 58.32
58.32 $\div$ 4 = 14.58
14.58+58.32 = 72.9 which is close enough
