480 m/s into km/hr in full method

Answer 1

HEY Buddy......!! here is ur answer
$1km \: = 1000m \: = > 1m = \frac{1}{1000} km \\ 1hour = 3600sec \: = > 1sec = \frac{1}{3600} hour \\ \\ \frac{1m}{1sec} = \frac{ \frac{1}{1000}km }{ \frac{1}{3600}hour } = \frac{3600}{1000} \frac{km}{hour} \\ \\ \frac{1m}{1sec} = \frac{18}{5} \frac{km}{hour} \\ \\ \\ 480 \frac{m}{sec} = 480 \times \frac{18}{5} \frac{km}{hour} = 1728 \frac{km}{hour}$
