Answer» QUESTION: How to convert $\dfrac{40}{46}$ km/h to m/s ? Answer: To convert $\dfrac{40}{46}$ km/h into m/s, we should MULTIPLY $\dfrac{5}{18}$ with it. Such as_ $(\dfrac{40}{46} \times \dfrac{5}{18} )$ $=( \dfrac{20}{23} \times \dfrac{5}{18} )$ $= ( \dfrac{10}{23} \times \dfrac{5}{9} )$ $= \dfrac{50}{207} m/s$ Explanation: To convert km/h to m/s we ALWAYS multiply the value by $\dfrac{5}{18}$ and from m/s to km/h we multiply the value by $\dfrac{18}{5} .$ This is because, 1 km = 1000 m 1 hour = 3600 seconds Let, the value be, N km/h. Hence, in m/s we get, $\dfrac{n\times 1000 }{1\times3600 } \\\\= \dfrac{n\times10}{36} \\\\= \dfrac{n\times5}{18} \\\\= \dfrac{5n}{18}$
