Question

I know I might sound stupid but I am 11 so my question is
What is 72km/hr into m/s

Answer 1

Hey There!

$1 \: km \: {hr}^{ - 1} = \frac{18}{5} m \: {second}^{ - 1}$

$72 \: kmph = ( \frac{72 \times 18}{5}) \: m \: {second}^{ - 1} \\ \\ = \frac{1296}{5} \: m \: {sec}^{ - 1} \\ \\ = 259.2 \: m \: per \: sec$
