-9- km-h-and -1- hour-3600- sec-1- km-1000- m-dfrac-1- km-m-dfrac-1000-3600-dfrac-5-18- m-s-therefore 9- km-h-dfrac-5-18- -times 9- m-sec-dfrac-5-2- or -2-5- m-sec-

Convert the following speeds into $$m/sec:$$
$$9\ km/h$$

$$9\ km/h$$
and $$1\ hour=3600\ sec$$
$$1\ km=1000\ m$$
$$\dfrac{1\ km}{m}=\dfrac{1000}{3600}=\dfrac{5}{18}\ m/s$$
$$\therefore 9\ km/h=\dfrac{5}{18} \times 9\ m/sec$$
$$=\dfrac{5}{2}$$ or $$2.5\ m/sec$$

Convert the following speeds into $$m/sec:$$$$9\ km/h$$

$$9\ km/h$$and $$1\ hour=3600\ sec$$$$1\ km=1000\ m$$$$\dfrac{1\ km}{m}=\dfrac{1000}{3600}=\dfrac{5}{18}\ m/s$$$$\therefore 9\ km/h=\dfrac{5}{18} \times 9\ m/sec$$$$=\dfrac{5}{2}$$ or $$2.5\ m/sec$$
